Cell Cycle

Question 0

Cyclin CDk complexes assist in the progression for g1 to S

Answer 0

Cyclin d and CDk 4 - phos rb which allows e2f to transcribe things ( cyclin e , thymidine kinase, dihydrofolate reductase)
Cyclin e and cdk2 allow it to go to s phase

Question 1

Tagged with Ubiquitin so it will go to the

Answer 1

Proteasome

Question 2

Cyclin CDk complexed assist in the progression for g2 to m phase

Answer 2

Cyclin a cdk2 - mitosis prophase
Cyclin b cdk1 ( activated by CDC 25 ) breaks down the nuclear envelope ( nuclear lamin breakdown) and initiations of mitosis

Question 3

Role of p21, p27, p57

Answer 3

Tumor suppressor genes that bind to and inactivate cyclin- CDk complexes ( p53 controls activation of p21)

Question 4

Answer 5

N oligosaccharide on asparagine
O oligosaccharide on serene and threonine
Mannose 6 phosphate for lysosome
