What is the cell cycle?Show answer
A dividing cell passes through a repeating sequence called the cell cycle. Most of the cycle is interphase, made of three phases: G1 (cell growth), S (DNA replication, when each chromosome is copied into two identical sister chromatids), and G2 (preparation for division). Division itself is the mitotic (M) phase, followed by cytokinesis, when the cytoplasm splits. Checkpoints control progression through the cycle, and loss of this control can lead to uncontrolled division and cancer.
What is mitosis?Show answer
Mitosis produces two daughter nuclei that are genetically identical to the parent cell and to each other. It is used for growth, tissue repair, and asexual reproduction. The stages are:
What is meiosis?Show answer
Meiosis produces four haploid gametes from one diploid cell, through two successive divisions, meiosis I and meiosis II, with only one round of DNA replication beforehand.
