READ: Mitosis

5. Lesson Summary

Chromosomes are coiled structures made of DNA and proteins. They form after DNA replicates and are the form in which the genetic material goes through cell division. Chromosomes contain genes, which code for proteins.
Cell division in eukaryotic cells includes mitosis, in which the nucleus divides, and cytokinesis, in which the cytoplasm divides and daughter cells form.
Mitosis occurs in four phases, called prophase, metaphase, anaphase, and telophase.
