Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.

The solution read: total proteins composed of 100 nucleotides is equal to 20100 The solution should read total proteins composed of 100 Amino acids is equal to 20100 I did have someone answer me earlier about how to obtain the solution, however, I just believe there is a typo is the solution text. We are not looking for nucleotides, we are looking for Amino acids. So it should read total proteins composed of 100 amino acids is equal to 20100. If we were looking for nucleotides it would read 4100
