Explanation: Mitosis occurs in 4 main divisions: Prophase, Metaphase, Anaphase and Telophase. Chromosomes appear as long coiled structures at the beginning of prophase and appear as single-stranded.

Are chromosomes single stranded?

Each chromosome contains a single double-stranded piece of DNA along with the aforementioned packaging proteins. ... However, when eukaryotic cells are not dividing — a stage called interphase — the chromatin within their chromosomes is less tightly packed.

What is a single stranded chromosome called?

Daughter chromosomes originate from a single stranded chromosome that replicates during the synthesis phase (S phase) of the cell cycle. The duplicated chromosome becomes a double-stranded chromosome and each strand is called a chromatid.
