Chromatid
Definition
The microtubule structure that aligns and separates chromosomes during division
Division of the cytoplasm following nuclear division
One of two identical copies of a replicated chromosome, joined to its copy at the centromere
Star-shaped formation of microtubules radiating from a centriole during early cell division
The point where two sister chromatids are held together
Correct Answer
(1) Chromatid,One of two identical copies of a replicated chromosome, joined to its copy at the centromere
(2) Centromere,The point where two sister chromatids are held together
(3) Cytokinesis,Division of the cytoplasm following nuclear division
(4) Spindle,The microtubule structure that aligns and separates chromosomes during division
(5) Aster,Star-shaped formation of microtubules radiating from a centriole during early cell division
Explanation
Essential cell division vocabulary:
- Chromatid - one arm of a replicated X-shaped chromosome; each was copied from the other during interphase
- Centromere - the junction holding two sister chromatids together; divides at metaphase
- Cytokinesis - physical splitting of the cytoplasm after nuclear division is complete
- Spindle - microtubule array extending pole to pole; aligns and separates chromosomes
- Aster - star-shaped microtubule radiations around centrioles in animal cells; absent in higher plant cells
