Question

Which is a function of cyclins? Cyclins are carbohydrates that regulate DNA replication during the mitosis phase of the cell cycle. Cyclins are glycoproteins that repair DNA in the beginning of cell cycle. Cyclins are proteins that regulate when and how often a cell divides. NextReset

Answer 1

The answer would be "Cyclins are proteins that regulate when and how often a cell divides". Cyclins belong to a family of proteins that control the progression of a cell through its respective cell cycle. This is initiated by activating cyclin-dependent kinase (CDK) enzymes which regulate transcription of RNA and process mRNA during mitosis.
