31 Easy

31 of 46

Understanding +4 | -1

Which is synthesized in

{G_1}

-phase?

View answer and explanation

Correct option: A

DNA polymerase

The correct answer is A (DNA polymerase) because DNA polymerase is essential for DNA replication, which the cell prepares for during the

{G_1}

phase.

32 Easy

Remembering +4 | -1

Which of the following events occurs during

{G_1}

-phase?

View answer and explanation

Correct option: B

Growth and normal function of cell

Option B (Growth and normal function of cell) is correct because the G1 phase is characterized by cell growth and normal cellular functions.

33 Easy

Remembering +4 | -1

Which of the following are properties of reserved cells?

View answer and explanation

Correct option: D

They are undifferentiated and they have capacity of cell division

Option D is correct because reserved cells are undifferentiated and retain the capacity for cell division, allowing them to contribute to growth and repair.

34 Easy

Which of the following phase of cell cycle is also known as the resting phase?

View answer and explanation

Correct option: D

Interphase

Option D (Interphase) is correct because interphase is the period between successive M-phases and is often referred to as the resting phase.

35 Easy

DNA replication in a cell cycle occurs during

View answer and explanation

Correct option: B

S-phase

Option B (S-phase) is correct because DNA replication occurs during the S-phase of the cell cycle.

36 Easy

What will be the amount of DNA in meiosis II product if meiocyte is containing 20 pg DNA in

G_1

phase?

View answer and explanation

Correct option: A

10 pg

Option A (10 pg) is correct because during meiosis I, DNA content halves, and during meiosis II, it halves again, so starting with 20 pg in G1, the product of meiosis II will have 10 pg.

37 Easy

I. The cells that do not divide further, exit

{G_1}

-phase to enter an inactive stage called …A… phase of the cell cycleII. The cells that are in

{G_{^2}}

-phase definitely continue with the …B… phase.Identify A and B to complete the given NCERT statements

View answer and explanation

Correct option: D

A - {G_0};B - M

The correct answer is D (

A - {G_0};B - M

) because cells that exit the cell cycle enter the

{G_0}

phase, and cells in

{G_2}

proceed to the M phase.

38 Easy

Remembering +4 | -1

Crossing over occurs during

View answer and explanation

Correct option: C

Pachytene

Option C is correct because crossing over, the exchange of genetic material between non-sister chromatids, occurs during the pachytene stage of prophase I in meiosis.

39 Easy

Remembering +4 | -1

A cell plate is laid down during

View answer and explanation

Correct option: A

Cytokinesis

Option A (Cytokinesis) is correct because the cell plate forms during cytokinesis to divide the cytoplasm.

40 Easy

The morphology of chromosomes can be studied most easily in

View answer and explanation

Correct option: B

Metaphase

Option B (Metaphase) is correct because chromosomes are most condensed and easily visible during metaphase.

41 Easy

41 of 46

Remembering +4 | -1

The phase between two successive M-phase is called

View answer and explanation

Correct option: D

Interphase

Option D (Interphase) is correct because interphase is the period between two successive M-phases in the cell cycle.

42 Easy

42 of 46

Understanding +4 | -1

Choose the correct statements regarding cell cycle
I. Interphase is called the resting phase
II. Interphase is the time during which the cell is preparing for division
III. The interphase is divided into phases, i.e.,G_1, S and G_2-phase
IV. Interphase represents the phase between the two successive M-phases
The option with correct statements is

View answer and explanation

Correct option: D

I, II, III and IV

The correct answer is D (I, II, III and IV) because all four statements accurately describe the interphase of the cell cycle.

43 Easy

Remembering +4 | -1

In a cell cycle, which structures serves as the site of attachment of spindle fibres?

View answer and explanation

Correct option: D

Kinetochore

Option D (Kinetochore) is correct because kinetochores are the sites where spindle fibers attach to chromosomes.

44 Easy

44 of 46

Understanding +4 | -1

What would be the change in the chromosome number, during S-phase?

View answer and explanation

Correct option: A

No change

The correct answer is A (No change) because during the S-phase, the amount of DNA doubles, but the chromosome number remains the same.

45 Easy

45 of 46

Remembering +4 | -1

During which stage of meiosis, do tetrads line up at the equator?

View answer and explanation

Correct option: C

Metaphase-I

Option C is correct because during metaphase I, tetrads (bivalents) align at the equator of the cell.

In which of the following stage of the cell cycle, the attachment of spindle fibres to kinetochores of chromosomes occurs?

View answer and explanation

Correct option: B

Metaphase

Option B (Metaphase) is correct because spindle fibers attach to kinetochores during metaphase.
