DNA Essay Examples - Free Research Papers on Study.Driver.
DNA has the genetic code for bodies, controls development of embryo’s, and is able to repair damage caused to itself. All DNA molecules have linked units called nucleotides. These nucleotides have sub-units that have 5 carbon sugars that are called deoxyribose. DNA is composed of four bases called adenine, thymine, guanine, and cytosine.DNA and RNA are found to be very important constituents in the living cell. DNA is the usual genetic material of the most organisms while RNA is the genetic material of some viruses. Most of the DNA is found in the chromosomes. They are also found in the cytoplasm as in mitochondria and chloroplast.Included: science essay content. Preview text: There are two kinds of NA. One ribonucleic acid (RNA) is so called because its sugar moiety is the pentose ribose. In the other, the sugar moiety is very similar but has one less oxygen atom than ribose and is called deoxyribose. This NA is called DN.
Long stands of double helical DNA can fit into the nucleus of a single cell because DNA is specially packaged through a series of compaction events to fit easily within cell nuclei.Even though the length of DNA per cell is about 100,000 times as long as the cell itself, it only takes up only about 10 percent of the cell’s volume.The DNA molecule, in order to condense, wraps itself around.Included: biology essay content. Preview text: A molecular model for DNA structure first proposed by J.D.Watson and F.H.C Crick (1953) has been universally accepted. They were awarded Nobel Prize for their discovery. The work of Crick and Watson has been supported by X-ray diffraction picture.
