Question
Chapter 15.4, Problem 3CC
Summary Introduction
To describe: The advantage of having checkpoints in the process of the cell cycle, where, the cell cycle can be stopped.
Introduction: The process of cell division takes place by the cell cycle. The cycle contains a number of cellular events that results in the production of numerous daughter cells from the pre-existing cells.

Name
HINT: when you are explaining mechanisms affected by mutations, think about molecular interactions, or
enzymatic functions, or conformational changes that are involved in the normal pathways, since these are the
aspects most likely to be affected by mutations or drugs, or viral proteins.
If a consequence of a mutation/drug/virus results in a cdk being more frequently active, then the cell cycle will
proceed at the given checkpoint. If the consequence of a mutation/drug/virus results in a cdk being
inactivated or inhibited, then the cell cycle is stopped at the given checkpoint.
