CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why is the Cell Cycle often represented as a circle?
A
Because it is easy to draw
B
Because cell cycles has a distinct beginning and end point
C
to highlight the checkpoints
D
to show that it repeats over and over
Explanation: 

Detailed explanation-1: -The cell cycle is a cycle, rather than a linear pathway, because at the end of each go-round, the two daughter cells can start the exact same process over again from the beginning.

Detailed explanation-2: -The cell cycle is a repeated pattern of growth and division that occurs in eukaryotic cells. The first phase represents cell growth while the last two phases represent cell division.

Detailed explanation-3: -The cell cycle is a repeating series of events that cells go through. It includes growth, DNA synthesis, and cell division. In eukaryotic cells, there are two growth phases, and cell division includes mitosis and cytokinesis. The cell cycle is controlled by regulatory proteins at three key checkpoints in the cycle.

Detailed explanation-4: -The cell cycle is the orderly sequence of events in which a cell duplicates its contents and divides into two new cells. The first part of the cycle is preparation for mitosis: the cell grows, accumulates nutrients, and, most importantly, copies all its chromosomes, so that there are two identical sets of DNA.

Detailed explanation-5: -The cell cycle is a repeating series of events that include growth, DNA synthesis, and cell division. The cell cycle in prokaryotes is quite simple: the cell grows, its DNA replicates, and the cell divides. This form of division in prokaryotes is called asexual reproduction.
