Homework Answers
The correct option is (e) i.e all of the above
It is because Cdk cyclin is present during all the stages of cell cycle i.e G0, G1, S, G2, and M phase.
- G0 phase is regulated by Cdk3
- G1 phase is regulated by Cdk2, Cdk4, and Cdk6
- S phase is regulated by Cdk2
- G2 phase is regulated by Cdk1, Cdk2
- M phase is regulated by Cdk 1

A. Explain how CDK activation in G1 leads to commitment to the cell cycle (the “restriction point” aka “R” in vertebrates aka START in yeast). Be sure to include G1-cyclin/CDK, Rb and E2F in your explanation. Include as much mechanistic explanation as possible. B. List two specific sequences/structures found in the DNA/chromosome, and their functions, that act to ensure that the number and morphology of chromosomes are constant from one generation of the cell to the next. Explain.

Yeast CDK (cdc2) has been fused with the mitotic cyclin (cdc13) and are together expressed from the cdc13 promoter (see figure below). Cells with this fusion go through the first cell stage but die in the next Gl. Explain hypothesize why cells with this fusion die in GI. If Cdc13-Cdc2 fused protein is injected in the cells described in "4" at the Gl from the second cell cycle they attempt to enter straight into M phase without passing through the...
