Which of the following can be a targets of phosphorylation by a cyclin-cdk? Select one: a. mitotic spindle-related proteins b. DNA replication proteins c. all answers are possible d. proteins that bind to the origin of replication e. mitosis proteins

Homework Answers

Answer #1

c ) all answers are possible

DNA replication machinery begin to assemble at origin of replication.

G1 cyclin - CDK complexes inactivates cdh1

G1 cyclin -CDK complex activate S phase cyclin - CDK expression

S phase cyclin / CDK activate preplication complex that began to assemble in step 1.S phase and G2 phase happen.

Cdc 25 phosphatase activate M phase cyclin / CDK .cell enters M phase enters to get metaphase.

APC / C and cdc20 traget securin for proteosomal degradation.cell advance from metaphase to anaphase
