Interpretation Introduction

Interpretation:

The effect of an increased Cro concentration on the expression of the λ repressor gene should be determined.

The effect of an increased λ repressor gene on the Cro gene expression should be determined.

The effect of an increased λ repressor on the expression of lambda repressor gene should be determined.

Concept introduction:

The lytic cycle is the rupture of the host cell, resulting in the release of a number of viruses. Bacterial viruses undergo lytic cycle only and are termed as the virulent bacteriophages. These viruses are the cause of their host cells death. Another life cycle of bacteriophage includes a lysogenic cycle. In this cycle, the viral DNA remains in the inactivated state even after various reproduction cycles of the host bacterium. After a certain time only, the viral DNA is released from the host’s cell DNA and undergoes lytic cycle.

Macmillan Learning 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.
