Document Summary

Macromolecules constructed out of long chains or stands of monomers called nucleotides. Functions primarily in the storage and transmission of genetic information. There are two types of nucleic acids found in living organisms, Deoxyribonucleic acid (dna), which serves as the genetic material of all cellular organisms. Ribonucleic acid (rna), which carries out the role of many viruses. In cells, information is stored in dna and is used to govern cellular activity through the rna messages. Each nucleotide in a strand of rna consists of three parts, The sugar and the nitrogenous base together form a nucleoside, so that the nucleotides of an rna strand are also known as ribonucleoside monophosphates. The phosphate linked to the 5" carbon of the sugar and the nitrogenous base is attached to the sugars 1" carbon. So the nucleotide of an rna or dna strand are connected by sugar-phosphate linkage, which are described as 3"-5"- phosphodiester bonds.
