Question

The cell cycle represents the coordinated sequence of events in the life of a cell from its formation to its division into two daughter cells. Most of the key events of the cell cycle are restricted to a specific time within the cycle.In this exercise, you will identify when various events occur during the cell cycle. Recall that interphase consists of the G1, S, and G2 subphases, and that the M phase consists of mitosis and cytokinesis.a. non-dividing cells exit cell cycleb. at this point, cell commits to go through the cyclec. DNA replicated. centrosome replicatese. mitotic spindle begins to formf. cell divides, forming two daughter cells

Answer 1

Answer:

Interphase : divided into three phases, i) G1 phase, ii) S phase and iii) G2 phase.

Mitotic phase: i) prophase, ii) metaphase, iii) anaphase and v) telophase.

Explanation:

interphase : divided into three phases, i) G1 phase, ii) S phase and iii) G2 phase.

G1 phase: cell decide whether to divide or not and prepare itself for replication of DNA and arrange replication machinery.  otherwise it goes to G 0 phase.

S phase: DNA replication occurs in this phase.

G2 phase: cell duplicates all their contents and prepares for mitotic phase.

Mitotic phase:

i) prophase- chromosome condensation occurs,

ii) metaphase - chromosome arranges in meta-plate and spindle binds to each chromosomes  at centromere.

iii) anaphase- chromosome separates from sister chromatids.

iv) telophase- chromosome moves to each ends and formation of nuclear membrane begins.

cytokinesis:  there is division of cytoplasm and forming two daughter cells.
