Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
DEFINE:What is interphase?
A
regular sequence of growth and division that cells undergo
B
first stage of the cell cycle
C
process in which DNA is copied
D
doubled rod of condensed chromatin
Explanation: 

Detailed explanation-1: -The interphase is the period when the cell is in a non-dividing state and this can be in different stages: the first gap (G1 ) between the last mitosis and the S phase (phase of DNA synthesis) and the second gap (G2) between the completion of the S phase and the next mitosis (M).

Detailed explanation-2: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth).

Detailed explanation-3: -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. The prefix inter-means between, so interphase takes place between one mitotic (M) phase and the next.

Detailed explanation-4: -Interphase. Also known as the resting phase of the cell cycle; interphase is the time during which the cell prepares for division by undergoing both cell growth and DNA replication.

Detailed explanation-5: -Interphase refers to the phase of the cell cycle in which a cell copies its DNA to prepare for mitosis. This phase is also referred to as the ‘daily living’ or the metabolic phase of the cell. Furthermore, in this stage, a cell gets nutrients and then metabolizes these nutrients.
