Question

multiple choice 1 point
what happens during the g2 phase?
chromosomes line up
cell grows and prepares for mitosis
dna is copied
spindle fibers attach

Explanation:

• Chromosomes line up: This occurs during metaphase of mitosis, not G2 phase.
• Cell grows and prepares for mitosis: The G2 phase is part of interphase. In this phase, the cell grows further, synthesizes proteins (like those needed for mitosis), and checks for DNA damage (to ensure it is ready for mitosis).
• DNA is copied: DNA replication occurs during the S - phase (synthesis phase) of interphase, not G2.
• Spindle fibers attach: This is an event that occurs during prophase (when spindle fibers start to form and attach to chromosomes) or prometaphase of mitosis.

Answer:

Cell grows and prepares for mitosis
