Compare and contrast the similarities, differences, and functions of DNA and RNA
The deoxyribonucleic acid (DNA) and the ribonucleic acid (RNA) play a fundamental role in preserving the genetic material of each individual. The DNA lies in the cell nucleus and stores the genetic information in a double strand of the nucleotides using the following paired combination of chemical bases: adenine (A) with thymine (T) and guanine (G) with cytosine (C). [A nucleotide contains a phosphate group, a pentose sugar (deoxyribose) and four organic bases- two purines (A and G) and two pyrimidines (C and T).] The DNA is also capable of replicating itself which preserves the information when a cell divides.
The RNA has a single strand of genetic material ...
The solution involves discussion on the similarities, differences and functions of DNA and RNA. It also includes a concise discussion on the feedback mechanisms that maintain homeostasis and examples of positive and negative feedback are given. References are included.
