Question 1
Which phase of the cell cycle occupies about 90 percent of the total cell cycle?
- AM phase
- BInterphase
- CCytokinesis
- DMeiosis
Show answerHide answer
Answer: B
Interphase occupies approximately 90 percent of the total cell cycle.
Question 2
During which phase of the cell cycle does maximum growth occur in the cell?
- AM phase
- BS phase
- CG1 phase
- DG2 phase
Show answerHide answer
Answer: C
The G1 phase is the main growth phase in which the cell produces proteins and organelles.
Question 3
In which phase of the cell cycle are the chromosomes duplicated?
- AMitosis
- BG1 phase
- CG2 phase
- DS phase
Show answerHide answer
Answer: D
The DNA of each chromosome is replicated during the S phase.
Question 4
Which of the following is NOT a characteristic of mitosis?
- AIt occurs in somatic cells.
- BIt results in genetically identical daughter cells.
- CThe chromosome number is halved in daughter cells.
- DIt results in the formation of two daughter cells.
Show answerHide answer
Answer: C
Mitosis does not halve the chromosome number; the daughter cells have the same chromosome number as the parent cell.
Question 5
At which stage of mitosis do chromosomes align in the centre of the cell?
- AProphase
- BMetaphase
- CAnaphase
- DTelophase
Show answerHide answer
Answer: B
During metaphase chromosomes align at the equator of the cell.
