Question

What are the major events that occur during each of the stages in the life cycle of a cell such as a skin cell, i.e., Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis?

Answer 1

Answer:

The interphase: DNA duplication; The prophase: Nucleus disappear; The metaphase: Chromosome line up at the middle of cell; The anaphase: Chromatids separation; The telophase: New cell membrane formed; The cytokinesis: Divided into two cell.

Explanation:

A cell cycle includes 4 main phases: G0 phase, Interphase, Mitotic or Meiosis phase, Cytokinesis.

• G0: cell has left the cycle and stop dividing
• Interphase: including G1, S, G2: cell increases its size, and the DNA is duplicated to prepare for cell division.
• Mitotic or Meiosis phase: including prophase, metaphase, anaphase, telophase. In this stage, the nucleus and materials are divided.
• Cytokinesis: Cell divides into two daughter cells.
