Question

Match the checkpoint to its function.

G₁/S checkpoint G₂/M checkpoint              Spindle‑assembly checkpoint

Answer Bank

ensures that each chromosome is attached to spindle fibers from opposite poles, maintains cell until necessary enzymes for replication are synthesized, detection of DNA damage after replicaion

What are checkpoints?

-transition points during the process of DNA replication that allow cell division to begin

-control points on protein synthesis that limit cancerous growth

-transition points during the process of chromosome separation that allow cell division to begin

-transition points during the cell cycle that ensure all cellular components are functioning properly

-periods of growth and development between cell divisions

Answer 1

1. G1/ S check point- maintain cells until necessary enzymes for replication are synthesised.
2. G2/M check point -detection of DNA damage after replication ,(and prevents cells from entering mitosis when DNA is damaged.)
3. Spindle assembly check point- ensure that each chromosome is attatched to spindle fibers from opposite poles.
4. check points are - transition points during cell cycle that ensures all cellular components are functioning properly. ( check proteins identify the issues and leads to arrest the cell cycle and allow adequate time to fix the problems on DNA)
