Explanation / Answer

Nucleic acids are polymers of Nucleotides. The monomers of nucleic acids consists of a phosphate group, a five carbon sugar, and nitrogenous base. DNA (deoxyribonucleic acid) provides directions for its own replication. It also directs cell activities by providing instruction for building proteins. A gene provides the directions to build a molecule of RNA (ribonucleic acid); the genetic instruction it carries are then translated into the amino acid sequence of a protein. A polynucleotide has a repeating sugar-phosphate backbone. The structure of DNA is a double helix, held together by the complementary base-pairing of cytosine with guanine, and adenine with thymine. RNA usually consist of single polynucleotide strand.
