|
|
The cells are at rest before the active division phase starts
|
|
|
The cells are producing more nuclei
|
|
|
The cells are synthesizing DNA, RNA, and proteins
|
|
|
The cells all go into G0 phase and withdraw from the cell cycle
|
Detailed explanation-1: -Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A cell in interphase is not simply quiescent.
Detailed explanation-2: -During the cell cycle, RNA and protein synthesis takes place during the G1 and G2 phases.
Detailed explanation-3: -Interphase is the longest phase in a typical cell cycle. The interphase is comprised of first growth phase or G1 phase, synthesis phase or S phase and second growth phase or G2 phase. In G1 phase, there is synthesis of RNA, enzymes, proteins, amino acids for histone formation, formation of nucleotides and ATP.
