Multiple Choice

In 1958, Francis Crick proposed that genes and their corresponding polypeptides are "colinear." Which of the following statements concerning the concept of colinearity is INCORRECT?

• A) Colinearity means that the linear nucleotide sequence of a given gene corresponds directly to the linear amino acid sequence in the corresponding polypeptide.
• B) The number of nucleotides in a gene should be precisely proportional to the number of amino acids present in the corresponding polypeptide.
• C) Colinearity generally holds true for the coding regions of prokaryotic viral genes.
• D) The vast majority of eukaryotic genes follow the concept of colinearity.
• E) The exception to colinearity between genes and polypeptides is the presence of untranslated sequences (UTRs).
