A sequence of how many nucleotides in messenger RNA makes a codon for an amino acid?

Options

  1. AThree
  2. BFour
  3. COne
  4. DTwo

Correct answer

A. Three

Step-by-step solution

The sequence of bases in mRNA are read in a serial order in groups of three at a time. Each triplet of nucleotides (having a specific sequence of bases) in known as codon. Each codon specifies one amino acid. Further since, there are four bases. therefore, 4³=64 triplets or codons are possible.
