Detailed explanation-1: -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-2: -In Streptomyces coelicolor, bldA encodes the only tRNA for a rare leucine codon, UUA. This tRNA is unnecessary for growth, but is required for some aspects of secondary metabolism and morphological development, as revealed by the phenotypes of bldA mutants in diverse streptomycetes.
Detailed explanation-3: -Leucine is an -amino acid, meaning it contains an -amino group (which is in the protonated −NH3+ form under biological conditions), an -carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain isobutyl group, making it a non-polar aliphatic amino acid.
Detailed explanation-4: -Amino acid Leucine is coded by 6 triplet codons: UUA, UUG, CUU, CUC, CUA and CUG.
