mRNA Comparison

A scientist studies the production of a key digestive enzyme in silk moths. The moths have one gene for this enzyme, and the scientist extracts mRNA transcribed from this gene as well as protein translated from it. The gene has three introns in its sequence.

Use the passage to answer the question.

Part B:

If the same scientist extracts the DNA for this gene and finds that it becomes methylated over the life of the organism, how will digestion change over time?

It will occur at lower pH.

It will rely more on this enzyme over time.

It will use methylated copies of the enzyme.

It will involve a lesser quantity of this enzyme over time.

If the DNA for the gene becomes methylated over the life of the organism, it is likely that the expression of the gene will be reduced or silenced. This means that there will be a lesser quantity of the enzyme produced over time. Therefore, digestion will involve a lesser quantity of this enzyme over time.
