DNA is a macromolecule that is used for instructions when creating proteins and other activities. It is because of this that DNA (and other nucleic acids) are essential for life to exist. DNA contains genetic code that primarily directs organelles in a cell to operate in a certain way. DNA also carries information regarding the traits of an organism. These traits are often passed from a parent cell to its offspring. This branch of biology is know as genetics. DNA also possesses a unique structure that allows it to perform all these actions. DNA is composed of hydrogen ,carbon, nitrogen, oxygen, and phosphorus. The monomers that make up nucleic acids are called nucleotides. Nucleotides consists of "a five carbon sugar molecule bonded to a nitrogenous base and a phosphate group." Nucleotides make up two kinds of nucleic acids, RNA and DNA. These types of nucleic acids are distinguishable by there function and there structure. DNA contains deoxyribose as a sugar base while RNA contains ribose as a sugar base. DNA is ideal for carrying genetic information and applying these instructions to facilitate life-sustaining functions. Eukaryotes (which contain a nucleus) have their genetic information stored in the nucleus in the form of chromosomes; while prokaryotes, (which do not contain a nucleus) have DNA floating in the cytoplasm in the form of plasmid. Nucleotides that make up DNA are very similar except for the difference in nitrogenous base that each one contains. These bases…
