How to bacteria divide?
They divide by binary fission.
What are chromosomes made of?
-Heterochromatin
-Euchromatin
-Nucleosome

Homologous
Eukaryotic Cell Cycle
-G1
-S
-G2
-M
-C
What stage of the cell cycle does growth occur in?
Interphase
What is Cytokinesis?
-The process of cleaving the cell into 2 equal halves
G1/S, G2/M and Late metaphase are?
The checkpoints of the cell cycle
What are CDKs?
They pair with cycling at different stages and phosphorylate other proteins.
They are controlled by phosphorylation
What kinds of genes can disturb the cell cycle when they are mutated?
-Tumor-suppressor genes
-Proto-oncogenes
Tumor-suppressor genes
The p53 protein is absent or mutated in many cancerous cells.
What cellular genes can lead to cancer when mutated?
Proto-oncogenes
