Created by StemPy LabHuman cells grown in culture divide about once every , and cell division proper (the M phase) lasts only about of that time. About what part of the cell cycle is interphase?
← All Quizzes
← Match the stages of mitosis in List-I with their key events in List-II.
List-I (Stage)
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
List-II (Key event)
I. Centromeres split, and the chromatids move to opposite poles
II. A nuclear envelope forms around each cluster of chromosomes, and the nucleolus, Golgi complex and ER reform
III. Spindle fibres attach to the kinetochores, and the chromosomes align at the equator
IV. Chromosomal material condenses, and the centrosomes begin to move to opposite polesAssertion (A): Mitosis gives daughter cells with half the number of chromosomes of the parent cell.
Reason (R): In mitosis, the number of chromosomes in the parent and in the progeny cells is the same, so it is also called equational division. →
