Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Chromatin is visible during this phase:
A
Interphase
B
Prophase I
C
Prometaphase I
D
Metaphase I
Explanation: 

Detailed explanation-1: -During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.

Detailed explanation-2: -During interphase, individual chromosomes are not visible, and the chromatin appears diffuse and unorganized.

Detailed explanation-3: -Cells spend most of their time in a stage called interphase. During this phase, the nuclear envelope surrounds the nucleus. There may be one or more nucleoli (dark, condensed regions) visible within the nucleus. The material around the nucleoli, contained within the nuclear envelope is DNA in the form of chromatin.

Detailed explanation-4: -In G1 phase, CHO xrs-5 cells were slightly more resistant to radiation than when in mitosis, but a significant proportion of their chromatin was found to remain in condensed form adjacent to the nuclear membrane.

Detailed explanation-5: -Answer and Explanation: Chromosomes become visible during interphase, which involves the first three stages of the cell cycle such as the G1, S, and G2 phases.
