Question

In the cell cycle, initiation of mitosis requires which of the following: O Incomplete DNA synthesis O Loss of centrioles O Complete loss of mitochondria O Asufficient amount of cyclin O A sufficient amount of rubisco

Answer 1

Cyclin name given to this protein because it continuesly synthesize and degrade at different stages of cell cycle. Synthesis of cycline activates Cdks (cyclin dependent kinase) by forming cyclin-Cdk complex. This cyclin-Cdk complex play important role in passing cell to the next phase of cell cycle. Hence a sufficient amount of cyclin is need for initiation of mitosis. So the forth option "A sufficient amount of cyclin" is the correct answer.
