What Checkpoint control mechanisms means in Biology A-Level, as defined for OCR.
Definition of Checkpoint control mechanisms
Check what you remember
Read the wording for your board, then hide it and explain Checkpoint control mechanisms in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Control points such as G1, G2 and the spindle assembly checkpoint monitor conditions such as DNA damage, completion of replication and chromosome attachment to the spindle, and can arrest the cycle.
