CELL DIVISION

THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why is it so important to replicate DNA?
A
so that each daughter cell is unique
B
to release energy
C
to make sure that the daughter cells are genetically identical to the parent cells
D
all of the above
Explanation: 

Detailed explanation-1: -Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. The replication process relies on the fact that each strand of DNA can serve as a template for duplication.

Detailed explanation-2: -Answer and Explanation: It is important that the daughter cells contain the same genetic information as the parent cells because those cells will have the same functional job as the cell they came from. Without the right genetic material, the cell may not be able to function correctly or even survive.

Detailed explanation-3: -Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits.

Detailed explanation-4: -Each new cell that is produced must have an exact copy of parental DNA. The daughter strands of DNA are part of a DNA molecule that will be in the daughter cells. This ensures that newly born cells are similar to parents and maintain their genetic identity.

Detailed explanation-5: -Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical-without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
