What phase is made up of G1, S and G2?
A
Interphase
B
M phase
C
Mitosis
D
Cytokinesis
Explanation: 

Detailed explanation-1: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

Detailed explanation-2: -G1 phase (Gap 1)-Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis)-Each of the 46 chromosomes are duplicated by the cell. III. G2 phase (Gap 2)-The Cell “double checks” the duplicated chromosomes for error, making any needed repair.

Detailed explanation-3: -Interphase – This phase includes the G1 phase, S phase and the G2 phase. M phase – This is the mitotic phase and is divided into prophase, metaphase, anaphase and telophase.
