When an extra nitrogenous base is inserted into the DNA sequence of a gene, the protein product of this gene is usually nonfunctional. Which of the following statements best explains why?

Question 1 options:

A .The inserted base signals enzymes to translate the DNA sequence rather than the RNA sequence into a protein.


B .The inserted base causes the codons in the mRNA sequence to be incorrect for the desired protein.


C. The inserted base sequence increases the rate of translation in the corresponding mRNA sequence, causing more errors.


D. The insert base sequence causes the DNA sequence to be transcribed into the RNA in the opposite direction.
