Detailed explanation-1: -The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. These names refer to the way the side groups, sometimes called “R” groups, interact with the environment.
Detailed explanation-2: -Amino acids are molecules used by all living things to make proteins. Your body needs 20 different amino acids to function correctly. Nine of these amino acids are called essential amino acids.
Detailed explanation-3: -Answer: Redundancy in the genetic code means that most amino acids are specified by more than one mRNA codon. For example, the amino acid phenylalanine (Phe) is specified by the codons UUU and UUC, and the amino acid leucine (Leu) is specified by the codons CUU, CUC, CUA, and CUG.
Detailed explanation-4: -Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha () carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
