Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the first stage of the cell cycle before cell division begins?
A
Interphrase
B
Replication
C
Metaphase
D
Telophase
Explanation: 

Detailed explanation-1: -Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide.

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: -Conclusion. Mitosis is the process of nuclear division, which occurs just prior to cell division, or cytokinesis. During this multistep process, cell chromosomes condense and the spindle assembles.

Detailed explanation-4: -Interphase is divided into the first growth (G1), Synthesis (S), and the second growth (G2) phases (figure 1). The growth phases are, as you may have suspected, for the growth of the cell, during the synthesis phase the DNA replication occurs in preparation for the second growth phase.
