What are the 5 phases of mitosis in order?

Prophase, Metaphase, Anaphase, Telophase, Cytokinesis

Where is DNA stored?

In the nucleus of a cell

What is the largest cell in a human body?

Ovum

How does DNA fit in a cell?

Chromosomes and chromatin

What is made with 8 histones?

Nucleosome

What is the center part of a chromosome called?

Centromere

What is the protein that is at the centromere which connects to the spindle fiber called?

kinetochore

What is the structue of a spindle fiber?

9 triplets of microtubles x 2 pairs ＝54

what is the place you pinch when cytokinesis?

Cleavage furrow

What is the average time for 1 cell cycle?

24h

What are the 2 phases of the cell cycle?

Interphase, Mitotic phase

What are 3 phases of interphase?

G1, S, G2

What happens in S phase?

DNA replication

What is helicase?

It unzips DNA, Breaks H bonds to form replication fork

What does topoisomerase do?

Cuts the phosphate backbone to allow it to unwind

What does primase do?

Add RNA primers to act as starting template

What does DNA polymerase3 do?

Creates okazaki fragments between RNA primers

What does DNA polymerase 1 do?

Replaces RNA primer with DNA

What does DNA Ligase do?

joins okazaki fragment's phosphate backbone

What happens during prophase?

Chromatin ⇒ centrosome, nucleus disappears, mitotic spindle forms

What happens during metaphase?

Chromosomes allign on imaginary plane at center

What happens during anaphase?

Chromosomes divide in two by kinetochore microtubules moving

What happens during telophase?

Nuclei reforms, chromosome ⇒ chromatin

What happens during cytokinesis?

Division of cytoplasm and 2 cells are formed

What is apoptosis?

cell suicides

What happens if a cell fails checkpoint?

goes to G0

What does G1 checkpoint do?

monitors DNA damage before replication

What does S checkpoint do?

Monitors DNA damage during replication

What does G2 checkpoint do?

Monitors DNA damage after replication

what does M checkpoint do?

Monitors spindle fiber errors

What disease happens if a cell checkpoint fails?

cancer
