Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The cell cycle can be described as
A
chaotic and composed of various phases that are virtually indistinguishable when viewed through a microscope.
B
identical in every kind of cell.
C
a sequence of events that continues constantly in all cells.
D
a pattern of distinct phases in a cell regulated by proteins.
Explanation: 

Detailed explanation-1: -The cell division cycle is the sequence of events by which a growing cell replicates all its components and divides them into two nearly identical daughter cells, so that each daughter cell receives all the machinery and information necessary to repeat the process [1, 2].

Detailed explanation-2: -A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Detailed explanation-3: -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.

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.
