mitosis worksheet
name: mathx
date:

1. label the following diagram with the phase of mitosis, (a) through (e), or the type of cell structure, (f) through (h), seen during mitosis.
2. during which stage of a cells cycle do the replicated chromosomes thicken and become visible?
3. during which stage of a cells cycle do the replicated chromosomes line up on the equator of the cell?
4. during which stage of a cells cycle do the chromosomes replicate?

Explanation:

1. Mitosis has distinct phases. Interphase is the preparatory stage before mitosis starts. Prophase is when chromatin condenses into visible chromosomes. Metaphase is when chromosomes line - up at the cell's equator. Anaphase is when sister chromatids separate. Telophase is the final stage where new nuclei form. Centrioles are involved in spindle - fiber formation, the spindle helps in chromosome movement, and chromatids are the replicated parts of a chromosome.
2. In prophase, replicated chromosomes condense and become visible under a microscope.
3. In metaphase, replicated chromosomes align on the equator of the cell.
4. Chromosome replication occurs during the S - phase of interphase, not telophase. The answer written is incorrect.

Answer:

1. a) Interphase; b) Prophase; c) Metaphase; d) Anaphase; e) Telophase; f) Nuclei; g) Spindle; h) Chromatids
2. Prophase
3. Metaphase
4. S - phase of Interphase
