Detailed explanation-1: -codon– a sequence of three nucleotides on a mRNA molecule that encode a specific amino acid. Anticodons are found on molecules of tRNA. Note:Each three-letter sequence of mRNA nucleotides (codons) corresponds to a specific amino acid, or to a stop codon.
Detailed explanation-2: -There are three termination codons that are employed at the end of a protein-coding sequence in mRNA: UAA, UAG, and UGA. No tRNAs recognize these codons.
Detailed explanation-3: -A sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid. Certain codons signal the start or end of translation.
Detailed explanation-4: -transfer RNA / tRNA Proteins are built from smaller units called amino acids, which are specified by three-nucleotide mRNA sequences called codons. Each codon represents a particular amino acid, and each codon is recognized by a specific tRNA.
