Question

Use the given information to select the amino acid attached to the 3′ end of tRNA during the process of translation, if the coding strand of the structural gene being transcribed has the nucleotide sequence ‘TCC’.

• A. Arginine
• B. Lysine
• C. Serine
• D. Glycine

Hint:

To determine the amino acid, first convert the coding strand to the mRNA codon, then match with the given codon table.

Answer 1

The Correct Option is C

The coding strand is 5′–TCC–3′, so the template strand will be 3′–AGG–5′. This is transcribed to the mRNA sequence 5′–UCC–3′, which is the codon for Serine, as provided in the codon table.
