Answer #1

Cyclins bind with cyclin dependent kinase enzyme and make a comolex, to activate protien kinase that are critical regulator of cell cycle. Cdks phosphyrylate its substrate and ensure the cell is ready to move on to next stage of cell cycle.

Option 3 is answer.

    Which of the following is NOT a checkpoint that controls the progression of the cell cycle? 0 Cyclins and cyclin-dependent kinases are proteins that are responsible for advancing a cell through the phases of the cell cycle. The G2 checkpoint checks for DNA damage and determines if all of the DNA is replicated. The metaphase checkpoint determines if all chromosomes are attached to the spindle apparatus. Cytokinesis involves the formation of cleavage furrow to separate the cells. The restriction point...

    1 You are a studying the progression of cells through the cell cycle. You are particularly interested in the cyclins E and A, both of which contribute sequentially to the same cell cycle transition. In this case one cyclin initiates the transition and the other completes the process. In these images you see cell extracts from Hela Cells. A) shows the levels of various proteins, while B) shows the amount of DNA in the cells, more DNA shifts this graph...

    Cancer cells often lack normal DNA damage response and cell-cycle control mechanisms. Why does this make them more susceptible to DNA-damaging chemotherapies? O Cancer cells will arrest in the cycle and will not grow further O Cancer cells with activating mutations in Ras will amplify the damage through the Ras signaling pathway Cancer cells might ignore the normal mechanisms that halt the cell cycle in response to damage, and subsequent division with damage leads to death, O Cancer cells have...

    Cancer biology 23. The levels of these proteins fluctuate dramatically as cells progress through the cell cycle. These fluctuations are tightly coordinated with the schedule of advances through the various cell cycle phases. For a particular subtype, extracellular signals, notably those conveyed by growth factors, strongly influence their levels. These proteins are: cdc25-like phosphatases b. Cdk kinases c. Protectins d. Cyclins 24. Which of the following best describes the biochemistry that correlates to one of the cell cycle functions of...
