An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. Covalent bonds join the sugar of one nucleotide to the phosphate group of the next nucleotide, forming the DNA strands sugar-phosphate backbone. Cells secrete acids and bases to maintain the proper pH for enzymes to do their work.

In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine. This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (RNA to protein). Despite the fact that it is a much more simple organism, an amoeba has 200 times more DNA than a human being. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Vernell attended the University of Central Florida, where he worked as a lab and lecture teaching assistant and personal tutor. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Adenine pairs with thymine, and cytosine with guanine.

These bases always pair together in the same way, A with T and C with G. When the two strands are put together each base finds its opposite pairing partner; this makes the two strands complementary to each other.

Although DNA was first discovered in 1869, by Swedish chemist Friedrich Miescher, it wasnt until 1943 that scientists were able to demonstrate the role it plays in passing genes from parent to child. Although most of the genetic information in DNA is passed on from parents to offspring, some simple organisms, such as bacteria, can also share genetic information with their neighbors through a phenomenon called horizontal gene transfer.. Attached to each sugar is one of four bases: adenine (A), uracil (U), cytosine (C) or guanine (G). The sugar in DNAs nucleotides is called deoxyriboseDNA is an abbreviation for deoxyribonucleic acid.
