Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Last year Diana was 5 feet tall. This year, Diana is 5’5” tall. What cellular process allowed her to grow?

A	Mitosis
B	Meiosis
C	Interphase
D	Cell division

Explanation:

Detailed explanation-1: -Multiply the percentage of time in each phase by the total time of the cell cycle (720 minutes) and this gives you an estimate of the time spent in each phase.

Detailed explanation-2: -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: -Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information. The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.

Detailed explanation-4: -The G1 phase is the longest in the cell cycle. It’s the beginning of the interphase. The cell prepares for division during the G1 phase.
