Hello,

These are all amazing questions and I have done my best to answer them all.

1. Why are these macromolecules (DNA and RNA) called nucleic ACIDS if they are made up of BASES?

ANSWER: Remember that DNA and RNA are made up of a phosphate backbone, a pentose sugar and a series of nitrogenous bases. It is the phosphate backbone of DNA and RNA that makes it an acid.

2.Discuss how the different FUNCTIONS of DNA and PROTEIN result in Different STRUCTURES. (or visa versa)

ANSWER: When it comes to DNA we are usually interested in the sequence of base pairs that ...
