MCQ
Codons that do not code for amino acids are:
  • A
    Phosphates
  • B
    ATP
  • C
    Start and stop signals
  • D
    Nonsense

Answer

  1. Nonsense

Explanation:

Codons are the nucleotide base triplets that specify a particular amino acid in proteins.

The codons that do cause termination of protein synthesis are known as stop codons.

The start codon specifies the first codon of mRNA transcript that is translated by a ribosome.

It codes for methionine in eukaryotes and a modified Met in prokaryotes. "AUG" is the most common start codon.

The codons that code for nothing, therefore there is no complementary tRNA for these codons, are nonsense codons.
