explain lamella, kinetochore,multinucleate---- with diagram
- Kinetochore is the structure that attaches a eukaryotic chromosome to the spindle apparatus for separation during mitosis.
- During mitosis prophase stage, the chromatids held together, at the narrow region called centromere. At this region, each chromatid has a disc like kinetochore, where the spindle microtubules join it. The two kinetochores of the chromosome face in opposite directions attach to opposite poles of the mitotic spindle. Kinetochores start, control and supervise the striking movements of chromosomes during cell division.
Multinuclei - These are the cells having two or more nuclei.
