Detailed explanation-1: -Each three-letter sequence of mRNA nucleotides corresponds to a specific amino acid, or to a stop codon. UGA, UAA, and UAG are stop codons. AUG is the codon for methionine, and is also the start codon.
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: -Multiple codons can code for the same amino acid. The codons are written 5’ to 3’, as they appear in the mRNA. AUG is an initiation codon; UAA, UAG, and UGA are termination (stop) codons.
Detailed explanation-4: -Answer and Explanation: Those mRNA codons code for Methionine (AUG), which is the “start” codon, Glycine (GGC), Glycine (GGU), Valine (GUA), and Isoleucine (AUC).
