Detailed explanation-1: -DNA is made of smaller subunits called nucleotides. Each nucleotide consists of three components: a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base.
Detailed explanation-2: -The DNA of microorganisms is made up of subunits called: nucleotides. The genetic code of DNA lies in the: nitrogenous base.
Detailed explanation-3: -As in all organisms, bacterial DNA contains the four nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T).
Detailed explanation-4: -Summary: The genomes or DNA of microbes contain defined DNA patterns called genome signatures.
Detailed explanation-5: -The key difference between amino acid and nucleic acid is that amino acid is the building block of proteins whereas nucleic acids is a macromolecule made out of nucleotides. Therefore, amino acids are small molecules while nucleic acids are macromolecules.
