Cell cycle and mitosis

Define the cell cycle.

• The sequence of events a cell undergoes throughout its life, including growth and division

• Only the period when the cell divides into two daughter cells

• The time between two mitotic events only

• A brief stage when DNA is copied and then the cell rests

What are the two main divisions of the cell cycle?

• Interphase and mitosis/cytokinesis

• Prophase and telophase

• G1 and G2

• Anaphase and metaphase

What are the three divisions of interphase?

• G1, S, and G2

• Prophase, metaphase, anaphase

• Telophase, cytokinesis, G0

• Mitosis, cytokinesis, meiosis

What takes place in G1 of interphase?

• The cell grows to full size and carries out regular functions

• DNA is replicated

• Organelles are duplicated before division

• The nucleus divides

What happens during the S phase of interphase?

• DNA is replicated

• The cell divides into two daughter cells

• Organelles are broken down

• The cell enters a resting state

What takes place in G2 of interphase?

• Organelles are duplicated and the cell grows before division

• DNA replication begins

• Chromosomes line up at the cell equator

• The cytoplasm divides

What is mitosis?

• Division of the nucleus

• Division of the cytoplasm

• Duplication of organelles

• Replication of DNA

What is the end result of mitosis?

• Two identical daughter cells

• Four genetically varied daughter cells

What are the three purposes of mitosis?

• Asexual reproduction, growth, and repair

• Energy production, respiration, and transport

• Protein synthesis, DNA repair, and meiosis

• Movement, digestion, and excretion
