CELL DIVISION

THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What would happen if interphase didn’t happen first?
A
Cells wouldn’t form correctly
B
Chromosomes wouldn’t form at all
C
There would not be enough chromosomes
D
Nothing would happen
Explanation: 

Detailed explanation-1: -If the interphase didn’t occur first, the cell would neither grow properly nor replicate its DNA.

Detailed explanation-2: -If chromosomes did not replicate during interphase then, when the new cells formed, each one would only have half of the necessary chromosomes. Part of cell division is dividing up the chromosomes between the two cells, and if you divide one set of chromosomes between two cells, each cell only gets half a set.

Detailed explanation-3: -A change in the number of chromosomes can cause problems with growth, development, and function of the body’s systems. These changes can occur during the formation of reproductive cells (eggs and sperm), in early fetal development, or in any cell after birth.

Detailed explanation-4: -During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
