Which of the Following is Not True of a Codon

Question

Which of the following is not true of a codon?
A)It consists of three nucleotides.
B)It may code for the same amino acid as another codon.
C)It never codes for more than one amino acid.
D)It extends from one end of a tRNA molecule.
E)It is the basic unit of the genetic code.

Accepted Answer

A codon is a sequence of three nucleotides that codes for a specific amino acid, and it is part of the mRNA molecule during protein synthesis. It does not extend from one end of a tRNA molecule. tRNA molecules have an anticodon sequence that recognizes and binds to the corresponding codon on the mRNA.
