During translation, nucleotide base triplets (codons) in mRNA are read in sequence in the 5’ → 3’ direction along the mRNA. Amino acids are specified by the string of codons. What amino acid sequence does the following mRNA nucleotide sequence specify? 5′−AUGGCAAG−3′ Express the sequence of amino acids using the three-letter abbreviations, separated by hyphens (e. g., Met-Ser-Thr-Lys-Gly).

Methionine-Alanine-Arginine-Lysine

Explanation: codon are tripple base code of nucleotide sequence specifying for a particular amino acid. There are 64 codons in all 61 determine a particular amino acid while 3 are stop codons. To start the translation process we have the start codon-AUG(methionine) and the three stop codon(UAA,UGA,UAG) which reads the end of translation.

For this sequence, AUGGCAAG

AUG- specifies Methionine the start codon

GCA- specify Alanine

AGA-specify Arginine

AAA- specify Lysine

correct answer is a. and d.
