Which of the Following is a Feature of Isoacceptor TRNAs

Question

Which of the following is a feature of isoacceptor tRNAs called suppressors?
A)They read suppressive codons and insert an amino acid.
B)They read nonsense codons and insert an amino acid.
C)They read anticodon codons and insert an amino acid.
D)They read mutated codons and insert an amino acid.

Accepted Answer

Isoacceptor tRNAs called suppressors are able to read nonsense codons (also known as stop codons) and insert an amino acid, thereby allowing for the translation process to continue beyond the premature stop codon. This can suppress the effects of a mutation that creates a premature stop codon in a gene.
