Hi,
Both questions are discuss and references at the end.
Hope it helps. Thanks for using BrainMass.

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 ...

Solution Summary

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.
