What regulates the activity of cyclin-dependent kinases (Cdks)? cAMP Specific cyclins Transcription factors The enzymatic activity of cyclins Histones

An kinase enzyme that is active only when attached to a particular cyclin.Group of answer choicesMPFCdkcyclin

"cell cycle control mechanism: mainly involved 2 components, cyclin- dependent protein kinases(CdKs) major component of cell cycle control mechanism. mechanism that helpthe cell to have a properly timed cell cycle and coordination of cell cycle various events. cdks depend on the cyclin subunit. it is a complex formed between cdks and cyclin, oscillations happen between these 2 ccomplexes responsible for the control of the cell cycle. s cyclin cdk complex, m cyclin cdk complexes. APC/C enzyme for cell cycle control mechanim also called anaphase promoting complex. SCF ubiquitinase important for cell cycle control mechanism. mechanism involved in cell cycle control. 1. phosphorylation of CDKs 2. proteolysis of cyclins 3. binding of the cdk inhibitor proteins: CKIs 4. changes in the transcript of genes that code for the regulatory protein

A cellular protein that occurs in a cyclically fluctuating concentration and that plays an important role in regulating the cell cycle.Group of answer choicesMPFCdkcyclin

Kinases are essential in the cell because they...  1. help regulate protein function through changes in protein phosphorylation status.   2. are enzymes that denature damaged proteins.  3. destroy second messengers, thereby turning off a signal transduction pathway.  4. provide a mechanism for amplifying the effect of the original signaling molecule.Group of answer choices122 and 31 and 4All of 1-4 PreviousNext

What role does the proteasome play in the regulation of the cell cycle?Group of answer choicesIt degrades ubiquitinated cyclin as part of a positive CDK/cyclin feedback mechanism.It degrades ubiquitinated CDK as part of a negative CDK/cyclin feedback mechanism.It degrades ubiquitinated cyclin as part of a negative CDK/cyclin feedback mechanism.It degrades ubiquitinated CDK as part of a positive CDK/cyclin feedback mechanism.
