Question

Does the cell cycle have a beginning and an end

Answer 1

Answer:

No, it is a cycle, so it repeats cyclic.

Explanation:

The cell cycle is divided into two main phases: interphase and mitotic phase.

Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division, formation of two daughter cells (mitotic phase).

Mitotic phase is subdivided into four phases:

• prophase, - nuclear envelope breaks down, condensed chromosomes are released

• metaphase- chromosomes are lined up, mitotic spindle is formed

• anaphase - the sister chromatids of each chromosomed move to the opposite ends of the cell

• telophase-final stage, nuclear envelope reforms
