Question

this is the cell cycle checkpoint that makes sure the correct number of chromosomes are present and attached to microtubules.
○ g1 checkpoint
○ g2 checkpoint
○ m checkpoint
○ i checkpoint

Explanation:

• G1 checkpoint: Checks for cell size, nutrients, growth factors, and DNA damage.
• G2 checkpoint: Checks for DNA replication completeness and DNA damage.
• M checkpoint (also known as the spindle - assembly checkpoint): Ensures that all chromosomes are properly attached to the spindle microtubules before the cell enters anaphase.
• There is no "I checkpoint" in the standard cell cycle checkpoints.

Answer:

M Checkpoint
