Botany - Cell Cycle and Cell Division Question with Solution | TestHub
Which of the following correctly related with given diagram?
(i) Sequence of cell cycle = G1− S – G2− M phase
(ii) A cell exits G1phase to enter an inactive stage - Quiescent stage or G0
(iii) G1phase is the interval between mitosis and initiation of DNA replication.
(iv) In G1phase DNA synthesis occurs.
Options:
Answer:
Solution:
The cell cycle is divided into two basic phases: A. Inter phase B. M Phase (Mitosis phase). The M Phase starts with the nuclear division, corresponding to the separation of daughter chromosomes (karyokinesis) and usually ends with division of cytoplasm (cytokinesis). The inter phase, though called the resting phase, is the time during which the cell is preparing for division by undergoing both cell growth and DNA replication in an orderly manner.
