Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which statement is NOT true about interphase?
A
It’s the longest phase of the cell cycle
B
During interphase organelles duplicate
C
During interphase, DNA replicates
D
During interphase, the chromatin condenses into chromosomes.
Explanation: 

Detailed explanation-1: -Final answer: The incorrect statement about interphase is ‘There is no cellular growth’.

Detailed explanation-2: -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).

Detailed explanation-3: -Answer and Explanation: The correct answer choice is C. The nucleus replicates. Replication of the nucleus does not happen during interphase.

Detailed explanation-4: -There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap). Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied. The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase.
