Question

Look at the highlighted condons on the mRNA. Use the menus to select the proper base pairs and make the anticodons. m R N A has a sequence of G A U C U A A G U A A U G C C G G A A U A C U A G C C U. The first highlighted codon is A U G. The second is G A A. The third is U A G.

Answer 1

The highlighted mRNA codons AUG, GAA, and UAG pair with anticodons UAC, CUU, and AUC, respectively, with the latter typically signaling a stop in protein synthesis.

Step-by-step explanation:

The question involves understanding how codon-anticodon interaction works in the context of translating mRNA into a sequence of amino acids during protein synthesis. The three highlighted codons are AUG, GAA, and UAG, which correspond to the start codon and two other codons specifying amino acids or a stop signal. To make the anticodons, we need to identify the bases that pair complementarily with each codon:

For AUG, the anticodon is UAC.

For GAA, the anticodon is CUU.

For UAG, the anticodon is AUC (which typically signals a stop in protein synthesis).

The anticodons are found on tRNA molecules, which help translate the language of RNA into the language of proteins.

Answer 2

The correct answer is - UAC, CUU, AUC

Step-by-step explanation:

Anticodon is a sequence of three bases present on the transfer RNA (tRNA). Anticodon is complimentary to the bases on messenger RNA (mRNA). During translation, anticodon pairs with the codon on a strand of mRNA.

Anticodon on the tRNA ensure that the correct amino acid will be added to making polypeptide chain during translation process of protein synthesis.

It is therefore, the anticodon are the complementary nucleotide base sequence of the codons on mRNA. Thus for the codes given on mRNA are AUG GAA and UAG, then the anticodons will be UAC, CUU and AUC on tRNA.
