Multiple Choice QuestionsWhich of the following phases correspond to the interval between mitosis and initiation of DNA replication?
S phase
G1 phase
G2 phase
M phase
M phase
B.
G1 phase
The G1 phase or Gap-1 phase is the first four phases of cell cycle that takes places in eukaryotic cell division. In this part of interphase, the cell synthesizes mRNA and proteins in preparation of subsequent steps leading to mitosis. G1 phase ends when the cell moves into the S phase of interphase.
Which of these is not a key feature of meiosis?
Meiosis involves two sequential cycles of nuclear and cell division
Meiosis involves pairing of homologous chromosomes
Two cycles of DNA replication occur during meiosis
Three is recombination between the paired homologous chromosomes
Three is recombination between the paired homologous chromosomes
The correct sequence of phases of cell cycle is
G1 → G2 → S → M
S → G1 → G2 → M
G1 → S → G2 → M
M → G1 → G2 → S
Cells in G0 phase :
enter the cell cycle
suspend the cell cycle
terminate the cell cycle
exit the cell cycle
Switch
