14.The molecules that make up a chromosome are?
413902
A chromosome, cosisting of a strands of DNA, or Deoxy ribose nucleic acid, is composed of a double sided chain of proteins known as nucleic acids. These acids, Adenine, Guanine, Cytosine and Thiamine may bond with any other nucleic acid in the ribs of the "ladder" of the DNA strand, but can only bond in certain pairs to form the "steps" of the ladder. Guanine only bonds to Cytosine, and Thiamine only bonds to Adenine. In the RNA molecule, which consists of only one "rung" of the "ladder", Thiamine is replaced by Uracil. Sets of these nucleic acids are what determines the traits expressed, "phenotypically", in the organism.

DNA is what makes up our genes.  It is several long chains (polymers) of molecules that contain a 'chemical code' that the body uses to make proteins (proteins are many types of molecules that are necessary for the body to make and run itself).  These long chains of DNA are grouped into 23 different chromosomes.  You have two pairs of each chromosome - one set of 23 from your mom and the other set of 23 from your dad.  So, in total, you have 46 chromosomes in each cell.\n\nEach cell in your body has the same DNA.  But a liver cell is different from a skin cell, etc.  That is because each cell type has access to only certain genes in your DNA (to make the proteins needed specifically for that type of cell).\n\nStructurally, DNA looks like a flexible ladder (like a rope ladder).  The runs of the ladder (the sides) are the long chains or polymers and consist of a sugar group connected to a phosphate group, connected to the next sugar group, and so on.  Between these side chains are pairs of 'bases' - Adenine, Thymine, Guanine, and Cytosine (A T G  C).  These are the actual code that contains the information in your genes.\n\nThe 'ladder' of DNA twists around itself to form a shape called a 'double helix'.\n\nI hope this is helpful to you.  Good luck!

A chromosome is a WHOLE DNA molecule, so an allele has one molecule (one chromosome)

Mitosis\n\nThe beginning of mitosis is called prophase. In early prophase, the centrosomes move toward opposite poles of the cell, organizing the spindle microtubules between them. The sister chromatids become visible in the nucleus as they condense. \n\nIn late prophase, the nuclear membrane breaks down and some of the spindle microtubules attach to the sister chromatids. The microtubules pull the chromatid pairs to the midline of the cell, or metaphase plate.\n\n•••\n\nThe chromatids remain lined up between the poles of the cell during metaphase.\n\n•••\n\nAnaphase begins when the pairs of sister chromatids separate. The separated chromatids are now called chromosomes, and move toward the poles of the cell.\n\n•••\n\nThe chromosomes arrive at the poles in telophase, and new nuclear membranes form around them.\n\n•••\n\nDivision of the cytoplasmic components is called cytokinesis. \n\nIn animal cells, cytokinesis occurs when a ring of actin and myosin filaments constricts the plasma membrane at the equator. Eventually, the parent cell is divided into two cells.\n\nAnimal Cytokinesis Movie (500K)\n\n\n\nIn plant cells, a number of small vesicles fuse at the metaphase plate to form the cell plate. Over time, the cell plate reaches across the cell and joins with the plasma membrane.\n\n•••\n\nThe process of mitosis and cytokinesis creates two separate cells, each with an identical set of chromosomes. After cytokinesis, the daughter cells will enter interphase.

46 chromosomes or 23 pairs of chromosomes per cell, consisting of 22 pairs of autosomes, and two sex chromosomes; considering the body has over a trillion cells...\n That is basically 46,000,000,000,000 chromosomes!\nThere are some rare cases when there is an extra chromosome(ex: Downsyndrome) or one less chromosome in each cell.

Chromosomes are tightly packaged bundles of chromatin.  Both are composed of DNA and carry genetic information.  Chromatin condenses to chromosomes when the cell is about to divide.

a molecule is a group of atoms, or, in some cases, a single atom.  an atom is made of protons, electrons, and neutrons.\n\na cell is the most basic unit of life.

centrioles are like:\n-2 magnets separating soduim(chromosomal part) and chloride(chromosomal part) from a solution of salt(stuff in nucleus) .

hey a correction there.... Genes are actually a small string of bases on a dna chain...so a dna chain has many genes.... and these dna are located in the chromosomes...not vice versa. chromsomes are in the nucleus of all cells.

Chromosomes are collections of genes which are coded in DNA molecules. Because after the split each daughter cell should be genetically identical to the parent cell, the cell division starts with the parent cell making a copy of each chromosome. \n\nEach chromosome now contains two identical copies of itself, called sister chromatids.\n\nDuring the dividing process the chromatids are split, and one half ends up in each of the two daughter cells.\n\nErrors in the cell splitting process are rare, but the process may go wrong, especially during the early cellular divisions of an embryon.

Chromosomes are what you see under a microscope when they are in a condensed state and preparing to divide.\n\nChromatid is either of the two daughter strands of a replicated chromosome.\n\nChromatin is complex of nucleic acids and proteins, primarily histones, in the cell nucleus that stains readily with basic dyes and condenses to form chromosomes during cell division.

a molecule of dna contains many nucleotides which contain a nitrogen containing base (adenice,guanine, cytosine or thymine), a deoxribose sugar, and a and a phosphate group

The DNA which carries genetic information in cells is normally packaged in the form of one or more large macromolecules called chromosomes.\n\nA chromosome, from the Greek χρώμα (color) and σώμα (body) is, minimally, a very long, continuous piece of DNA (a single DNA molecule), which contains many genes, regulatory elements and other intervening nucleotide sequences.

12 linear chromosomes in the nucleus, plus plasmids in the ~100 chloroplasts, and circular chromosomes in the ~100mitochondria. Note that each mitochondria has many identical chromosomes.

Store genes on chromosome\n \nOrganize genes into chromosomes to allow cell division.\n\nTransport regulatory factors & gene products via nuclear pores \n\nProduce messages ( messenger Ribonucleic acid or mRNA) that code for proteins \n\nProduce ribosomes in the nucleolus \n\nOrganize the uncoiling of DNA to replicate  key genes\n\n\n\n...and it's nucleus (777 above)
