transcription in cells makes RNA copies of DNA.

They have both.  Their genome is made out of DNA as is the genome of all other living organisms.  They transcribe DNA into RNA for further use in protein synthesis.  Also they have ribosomes, which are partially composed of RNA.

No, definately not worth the money. DNA/RNA is not required in your diet, your body makes all the DNA and RNA you need.

First off jamesmusik84's is completely wrong. Please don't consider any of it. The second answer is along the right path, except I have no idea what the reference to antibiotic is suggesting and some viruses have RNA genomes but many more have DNA genomes. And as far as bacteria go, both RNA and DNA are present inside there cells.\n\nSo, the answer to your question. Let's start this way: Bacteria are small single-celled organisms. Unllike eukaryotic cells (like the ones that make up animals, plants, fungi and many single-celled organisms such as yeasts) which package their genetic material (DNA) in membrane structures called nuclei, bacteria (which are also referred to as prokaryotes) don't have a nucleus. Bacteria also don't have other organelles which are found in eukaryotes, such as endoplasmic reticulum, mitochandria, chloroplasts, golgi bodies, etc. But like eukaryotes, bacteria do have an outer lipid membrane.\n\nSo, you can think of bacteria of little fluid filled sacs. Along with eukaryotic, bacteria are an example of "cells" which are the smallest unit of living things on earth.\n\nViruses, on the other hand, do not have an outer membrane. They don't the capacity to make their own proteins. They don't have the capacity ot replicate or metabolize on their own -- of which bacteria (and eukaryotes) do. It's for this reason that we don't consider viruses "living" things. Viruses have to "infect" a cell -- injecting its genetic material inside -- and use the cell's metabolic machinery to reproduce.\n\nViruses are essentially small protein "capsules" that have a piece of genetic information packaged inside. Because viruses are required to infect a cell to propogate themselves, they are classified as obligate intra-cellular pathogens.\n\nViruses tend to only infect specific cell types. Some infect bacteria. Some infect plants. Others infect animals. The specificity of what a virus can infect is goes beyond whether they can infect bacteria, plants or animals. Usually viruses have to infect a very specific animal, plant or bacteria. And even in the case of viruses that infect animals and plants, not only do the infect specif animals, they are usually limited to a few cell types whithin that animal.\n\nTake HIV for example: to the best of my knowledge HIV only infects humans (i.e. the "H" in HIV -- Human Immunodeficiency Virus). But it doesn't just infect any human cell. HIV only infects white blood cells -- specifically a class of white blood cells called T cells (there are many other "classes" of white blood cells including such things as B cells, NK cells, neutrophils, basophils, eosinophils and macrophages).\n\nI hope this sheds some light on the matter.

DNA is a substance just like RNA and protein are. In a cell's nucleus DNA is "transcribed" into RNA (another substance), RNA (not DNA) is then "translated" into protein.

no \nthe lack of it might be.\nit is related to the attachment of the poly-A tail to the mature m-RNA strand.

those two are proteins and nucleic acids (DNA and RNA).  those two are present in all the living beings (the only problem with them is, that in viruses they are present - but some scientists belive that viruses are not living materia).\n\nthere are other organic components in living materia, such as lipids, carbohzdrates, vitamins, ferments etc.\n\nand those organic moleculas are composed of minerals - those which are listed in the first answer.

This goes to the core of biological and evolutionary theory.\n\nDNA is elements arranged into nucleic acid molecules, arranged in a code (see first link). This code is directly used by a couple of RNA molecules to build protein molecules, ie enzymes (see link two).\n\nProtein molecules make up most of our body structure themselves, but for other parts (made from other molecules - which are combinations of elements), enzymes are used to arrange the correct structure.

FIrst of all DNA is not a mixture of nucleic acids and proteins,  but protein does hold DNA together, and certain proteins (histones) that hold DNA together need to be activated in order to open up essentially in order to allow for transcribtion of DNA into messanger RNA.  However, if you reverse a protein to DNA you find where it correlates to on the DNA strand and the nucelotide sequence, thus this may be a possible reasoning to the question. For the most part i would not say proteins are a window to DNA but instead a key to understanding it.

They both have to do with RNA... I had this on a bio quiz but I forgot...\n\nMRNA: RNA transcribed from the DNA making up a gene. It transmits genetic information from the nucleus to the cytoplasm, where it directs the synthesis of proteins.\n\nTRNA: RNA molecules that carry amino acids to sites on ribosomes where proteins are synthesized.

Just a clarification-DNA is composed of nucleic acids, not amino acids.  Amino acids are the building blocks of proteins.

Your question could have many different answers:\n\n1. RNA is better suited for a translation step because it is single stranded.\n2. DNA is a better information storage molecule because it is double stranded, and less easily hydrolyzed in physiological conditions.  \n3. RNA is great for regulating the degree of protein synthesis because it is easily hydrolyzed.  This means that it will degrade after a short period.  If it doesn't degrade, then whatever protein it encodes will be forever synthesized and that's bad.\n4. RNA can be made in multiple copies so that lots and lots of protein can be synthesized if necessary.  \n5. DNA is in the nucelus, and if proteins were directly translated from DNA, then they would have to be transported out.  (An energetically expensive process).\n6. The current "RNA-world hypothesis" suggests that life began with RNA.  RNA is great because it can be used for information storage and catalysis, but as mentioned, it degrades easily.  Thus, DNA came into the picture.  But, RNA still exists as a messenger molecule.  (RNA does a lot of other things in the cell too)\n\nThere are more possible answers, but in essence, transcription and translation are separate steps because DNA and RNA are better at different things.  DNA is good at storage, but it is difficult to regulate the degree of protein synthesis with only DNA (it can be done though).  Another way to look at it is that DNA is a guide book, but RNA is necessary to actually do the job.

d(eoxyribo)n(ucleic) a(cid) \nDNA is a nucleic acid that carries the genetic info in the cell and is capable of self-replication and synthesis of RNA. DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics. \n\nr(ibo)n(ucleic) a(cid) \nRNA is a  polymeric constituent of all living cells and many viruses, consisting of a long,single-stranded chain of alternating phosphate and ribose units with the bases adenine, guanine, cytosine, and uracil bonded to the ribose. The structure and base sequence of RNA determines protein synthesis and the transmission of genetic information.

rRNA or robosomal RNA are RNA present in ribosomes, do not code for proteins but help ribosomes in protein stnthesis or translation.
