Explanation:
Detailed explanation-1: -The three-letter nature of codons means that the four nucleotides found in mRNA-A, U, G, and C-can produce a total of 64 different combinations. Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis.
Detailed explanation-2: -This leads to a total of 10 codons in the mRNA sequence AUGGCAGUGCCA as AUG, UGG, GGC, GCA, CAG, AGU, GUG, UGC, GCC, CCA.
Detailed explanation-3: -For example, the sequence AUG is a codon that specifies the amino acid methionine.
Detailed explanation-4: -The amino acid the mRNA codon AAG codes for is Lysine.
