Chromatid (Noun)
Meaning
One of two identical strands into which a chromosome splits during mitosis.
Classification
Nouns denoting body parts.
Examples
- Each chromosome replicates during interphase to produce two identical sister chromatids that are held together at the centromere.
- During prophase of mitosis, the chromosomes condense and become visible, and the two chromatids that make up each chromosome can be distinguished.
- As the centromere divides during anaphase, the two sister chromatids are pulled to opposite poles of the cell by the microtubules.
- Each new daughter cell will receive a complete set of chromosomes, each consisting of one chromatid that originated from the parent cell.
- When a cell enters the cell cycle and begins to replicate its DNA, the two resulting chromatids remain joined together until mitosis.
