Question
Chapter 26, Problem 3P
Interpretation Introduction
Interpretation:
The major differences between a regulon and an operon should be explained.
Concept introduction:
- An operon is defined as the set of genes which are linked. These are controlled by regulatory processes and are present near the structural genes of the deoxyribonucleic acid (DNA) in the cell.
- A regulon is defined as the set of genes that are unlinked. These are controlled by common regulatory processes and are scattered throughout the genome in the cell.

Cholesterol synthesis begins with the formation of mevalonate from acetyl CoA. This
process activates mevalonate and converts it to isopentenyl pyrophosphate.
Identify the atoms in mevalonate and isopentenyl pyrophosphate that will be labeled
from acetyl CoA labeled with 14C in the carbonyl carbon. Place 14C atoms and C atoms
to denote which carbon atoms are labeled and which are not labeled.
