What is Chromosomes?

Also known as: chromosome · karyotype

Definition 64.1 Primary & Middle School Biology · Chapter 64 — Chromosomes

Between divisions the same threads run loose and invisible — working state; at division they condense — moving state. Photographed and sorted, a cell’s chromosomes make its karyotype: the full deck, laid out.
