Indicate whether the sentence or statement is true or false.

A codon consists of four nucleotides.

Answer: The statement is false

Explanation: A codon consists of three nucleotides instead of four. Codons are triplets of nucleotides on an mRNA molecule that code for specific amino acids. Each amino acids are specified by at least one codon. Some amino acids are specified by one codon, some are specified by two or more codons. The phenomenon whereby more than one codon specifies one amino acid is known as the degeneracy of the codons.
