Which of the following statements about prokaryotes is correct?
830084
hmm none of them sound completely correct, but A and E seem the most correct and E is probably the one considered correct by the person doing the grading, since A is rare among bacteria, but still occurs, and  E is rare that prokaryotes do not use this method of reproduction.

There are two general classes of cells: prokaryotic and eukaryotic. The evolution of prokaryotic cells preceded that of eukaryotic cells by 2 billion years.\n\nHumans, of course, are an example of multicellular eukaryotes. \nThe major similarities between the two types of cells (prokaryote and eukaryote) are: \nThey both have DNA as their genetic material. \nThey are both membrane bound. \nThey both have ribosomes . \nThey have similar basic metabolism . \nThey are both amazingly diverse in forms. \nThe major and extremely significant difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus and membrane-bound organelles , while prokaryotes do not. The DNA of prokaryotes floats freely around the cell; the DNA of eukaryotes is held within its nucleus. The organelles of eukaryotes allow them to exhibit much higher levels of intracellular division of labor than is possible in prokaryotic cells. Additional obvious differences between prokaryotes and eukaryotes include: \n\nSize \nEukaryotic cells are, on average, ten times the size of prokaryotic cells. \nGenomic composition and length \nThe DNA of eukaryotes is much more complex and therefore much more extnsive than the DNA of prokaryotes. \nCell Wall \nProkaryotes have a cell wall composed of peptidoglycan, a single large polymer of amino acids and sugar . Many types of eukaryotic cells also have cell walls, but none made of peptidoglycan. \n\n\nCell theory :\n1.All organisms are made up of one or more cells. \n2.The cell is the fundamental unit of structure and function in living things. \n3.All cells are essentially the same in chemical composition

Maybe prokaryotes. But I'm not sure... I think there's still a debate about them cause they're not really living creatures... They are "alive" when they are inside a host, but otherwise, they're just lifeless proteins.. :)

Just to add to Acraz's answer, Plants and fungi are also made up of eukaryotic cells. \nOnly bacteria are prokaryotic.

Prokaryotic cells do not have the same lifespans as eukaryotic cells. This is because they do not carry out the same metabolic functions as eukaryotic cells.

Protein is correct - the interesting thing is that every plant and animal on earth uses the same genetic code to produce the same proteins. Bacteria are so distantly related that they have a few substitutions in their genetic code - but it's still very similar to our own. \n\nThere is  aother substance that DNA produces - but not with the same coding. It's rarely mentioned because we don't know as much about its role - it's RNA. In fact there are probably more RNA genes then protein coding genes.

Nuclear?  Nuclear envelope?  Nuclear membrane? \n\nThe word 'eukaryote' means 'true nuclei'.  They are talking about the membrane which surrounds the nucleus of the cell.  This is not present in Prokaryotes.

Hey, this is a question I asked my professor, how funny, lol. \n\nFirst of all, it's important to note the differences between a prokaryotic and a eukaryotic cell.  \n\nCells that lack a membrane-bound nucleus are called prokaryotes (from the Greek meaning before nuclei). These cells have few internal structures that are distinguishable under a microscope. Cells in the monera kingdom such as bacteria and cyanobacteria (also known as blue-green algae) are prokaryotes. Prokaryotic cells differ significantly from eukaryotic cells. They don't have a membrane-bound nucleus and instead of having chromosomal DNA, their genetic information is in a circular loop called a plasmid. \n\nTake a look at this picture:  http://library.thinkquest.org/C004535/media/prokaryote.gif\n\nEukaryotic cells comprise all of the life kingdoms except monera. They can be easily distinguished through a membrane-bound nucleus.  Eukaryotic cells also contain many internal membrane-bound structures called organelles. These organelles such as the mitochondrion or chloroplast serve to perform metabolic functions and energy conversion. \n\nTake a look at this picture:  http://library.thinkquest.org/C004535/media/eukaryote_animal.gif\n\nFor a brief and quick response, ...a eukaryotic cell is a larger cell with distinctly more organelles within the cell.  They differ in size greatly :)

DNA has phosphate sugars so no. ATP stands for adenotriphosphate so no. membranes consists of phospholipids. rna is the same as DNA in constituents with uracil base change and more oxygen.\n\nso none.\n\nin return for the answer can you let me know what you think of my essay...\n\nEvolutionary scientific discoveries unwittingly make the human creation in the book of Genesis feasible to the point of affirmation.\n\nIntroduction\n\nIn the beginning “male and female He created them.” (Genesis 1, 27) This statement has been contested ever since the Age of Enlightenment when human beings with their development of knowledge set about challenging God’s authority in the world around them. Immanuel Kant’s motto “Dare to know” really symbolises the dominant modernistic attitude that was and continues to be embraced by humanity. God has no problem with us gaining knowledge- he invented science and has got it to a perfect art seeing as he spoke all the necessary components into being. Indeed knowledge is God-given to the point that it is one of the fruits of the spirit. Besides, if God really wanted us to remain ignorant of the world he wouldn’t have given us the Word. I therefore want to emphasise that it is only when we think we got here on our own, without God that we come into dispute with God and the truth. But rejection is nothing new to God, who is neither surprised nor shocked by our choices or actions. Before God even created the world he had sent his son to die “it was the Lord’s good plan to crush him” (Isaiah 53, 10) and before he created the universe God knew we would “turn our backs on him and look(ed) the other way.” (Isaiah 53, 3). The fact that Charles Darwin’s Origin of Species caused some controversy and drove people to reject Jesus as the truth was not a ‘heavy blow’ for Him. For one thing, and I say this tongue-in-cheek, if God is anything like me he had probably gotten ‘bored’ of waiting. After all there’s quite a bit of waiting between before the Planck epoch (for those who are interested the Planck epoch is the time between zero and 10-43 seconds of the beginning of the universe) and 1859! Regardless of this publication and the later The Descent of Man (1871) His plan would still prevail over all His creation. The plan had already succeeded before we emerged on day six. Everything else had already been put in place: Jesus’ death and resurrection and all the animals and plants. EVERYTHING! God did NOT need our help or our approval and if he didn’t need it then, he certainly doesn’t need it NOW. What is interesting is that as God allows our knowledge to deepen and technology to improve evidence, particularly genetic and fossilised, appears to be pointing towards the feasibility if not the affirmation of the ‘story’ of Adam and Eve foretold in Genesis.\n\nAssumptions of the Author\n\nBefore I go any further I am making the following interpretations and/or assumptions:\n\n•Evolution (at least in humans) does occur but only within species. I believe that whilst other animals may evolve we wouldn’t as we are God’s chosen creation made in His image. He never changes and thus nor have (or will) we. Within our species implies that if women suddenly found blue-eyed men to be a turn-off generation after generation so that blue-eyed men could not pass on their seed, humans as a species would have less and eventually no blue eyed alleles but they would not in becoming predominately brown or green-eyed become a new species.\n•Evolution in definition is always ‘survival of the fittest’ where the most advantageous traits are passed on to the next generation. By dramatically becoming less hairy- so from having fur (ape) to being bare (Homo sapien)- the human race would have a severe disadvantage in that fur keeps you warm in a cold climate and cool in a hot one. Loss of fur is of course risky in a glacial-inter glacial planet cycle. The only reason for the fact we have no fu

In the nucleus for eukaryote, and just floating around in a prokaryote.  The prokaryotes are Monera (bacteria) and Archaea.  More complex creatures are eukaryotes.\n\nSo nucleus is probably the answer you're looking for.

Cyanobacteria are prokaryotes (single-celled organisms) often referred to as "blue-green algae." While most algae is eukaryotic (multi-celled), cyanobacteria is the only exception. Cyanobacteria obtain their energy through photosynthesis. They are not strictly unicellular, but can be found in colonial and filamentous forms, some of which differentiate into varying roles. For example, cyanobacteria specialized for nitrogen fixation are called heterocysts. \n\nCyanobacteria are very old, with some fossils dating back almost 4 billion years (Precambrian era), making them among the oldest things in the fossil record. They played a key role in increasing the amount of oxygen in the Earth's atmosphere. For almost 2 billion years, cyanobacteria and other prokaryotes were the only organisms on Earth, eukaryotes not having evolved yet. Conceivably, life on other plants, if it exists, may consist of prokaryotes and no eukaryotes. Due to their simplicity, prokaryotic cells are about 1000 times smaller than eukaryotic cells. \n\nhttp://www.wisegeek.com/what-is-cyanobacteria.htm

Deoxyribonucleic acid (DNA) is a nucleic acid —usually in the form of a double helix— that contains the genetic instructions specifying the biological development of all cellular forms of life, and many viruses. DNA is a long polymer of nucleotides (a polynucleotide) and encodes the sequence of the amino acid residues in proteins using the genetic code, a triplet code of nucleotides. DNA is thought to date back to between approximately 3.5 to 4.6 billion years ago [1].\n\nIn complex eukaryotic cells such as those from plants, animals, fungi and protists, most of the DNA is located in the cell nucleus. By contrast, in simpler cells called prokaryotes, including the eubacteria and archaea, DNA is not separated from the cytoplasm by a nuclear envelope. The cellular organelles known as chloroplasts and mitochondria also carry DNA.\n\nDNA is often referred to as the molecule of heredity as it is responsible for the genetic propagation of most inherited traits. In humans, these traits can range from hair color to disease susceptibility. During cell division, DNA is replicated and can be transmitted to offspring during reproduction. Lineage studies can be done based on the facts that the mitochondrial DNA only comes from the mother, and the male Y chromosome only comes from the father.\n\nEvery person's DNA, their genome, is inherited from both parents. The mother's mitochondrial DNA together with twenty-three chromosomes from each parent combine to form the genome of a zygote, the fertilized egg. As a result, with certain exceptions such as red blood cells, most human cells contain 23 pairs of chromosomes, together with mitochondrial DNA inherited from the mother.

The earliest evidence of procaryotic bacteria are from about 3.8 billion years ago in stromatolites from cherts in Western Australia (the Warrawoona group). Unicellular eucaryotes can be dated from about 1.6 to 1.8 billion years ago.
