Question

Which of the following statements is true for protein synthesis (translation)?

• A. Amino acids are directly by $m-RNA$
• B. The third base of the codon is less specific
• C. Only one codon codes for an amino acid
• D. Every $t-RNA$ has more than one amino acid attachment

Answer 1

Answer: (B)

The third base of the codon is less specific

A code determines the order of joining of amino acid residues The code is in the form of triplets known as codons.
Out of three bases in a codon, the first two bases are specific to a particular amino acid.
The third base of the codon is less specific.
Thus, the statement (B) is correct.
