Nucleotides. A single nucleotide contains a phosphate group, deoxyribose or ribose (depending on the nucleic acid) and a nitrogen base, which can be adenine, guanine, cytosine â¦ , thymine, and uracil. These monomers combine to form polymers known as DNA or RNA.
Much of the answer lies in the genes, the basic units of heredity. Each gene is a specific segment of DNA, occupying a fixed place on a chromosome. Genes contain the chemical information needed to create different kinds of proteins. segment of DNA, occupying a specific place on a chromosome, that is the basic unit of heredity. Genes act by directing the synthesis of proteins, which are the main components of cells and are the catalysts of all cellular processes.
