A
Mitosis(PMAT)
8
Q
Prophase
A
DNA condenses, chromosomes are visible
9
Q
Metaphase
A
Chromosomes line up down the middle with spindle fibers
10
Q
Anaphase
A
Sister chromosomes separate into individual ones
11

Telophase
A
Two nuclei form, chromosomes lose shape

Chromatin Structure
A
DNA wrapped around histones, then nucleosomes
14
