Individuals with one form of lactose intolerance do not produce the enzyme lactase because the gen coding for the production of lactase is
turned off in their cells. As a result, which of the following processes
does not occur for the gene?
Select one:
a. Transcription
b. Hydrogenation
c. Replication
d. Hydrolysis

Transcription - A

Explanation:

This problem is talking about the lac operon and the gene expression of lac operon. If the gene is turned off, then transcription, the generation of mRNA won't occur.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion
