A sequence of how many nucleotides in messenger RNA makes a codon for an amino acid?
A sequence of how many nucleotides in messenger RNA makes a codon for an amino acid?
Three
Four
One
Two
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) is known as codon. Each codon specifies one amino acid. Further since, there are four bases, therefore, $4^{3}=64$ triplets or codons are possible.
