CELL DIVISION AND CANCEROUS CELLS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During interphase to prepare for mitosis, a cell grows, duplicates organelles, and ____
A
copies DNA
B
divides the nucleus
C
divides the cytoplasm
D
produces a new cell
Explanation: 

Detailed explanation-1: -During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells.

Detailed explanation-2: -Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

Detailed explanation-3: -The G1 phase stands for gap 1 and is when organelles replicate and the cell grows. The S phase stands for synthesis and is when DNA is replicated.

Detailed explanation-4: -At the molecular level, however, interphase is the time during which both cell growth and DNA replication occur in an orderly manner in preparation for cell division. The cell grows at a steady rate throughout interphase, with most dividing cells doubling in size between one mitosis and the next.

Detailed explanation-5: -Before a eukaryotic cell divides, all the DNA in the cell’s multiple chromosomes is replicated. Its organelles are also duplicated. This happens in the interphase.
