The sequence of cell cycle is :

A. S, M, Gd₁d and Gd₂d B. Gd₁d , S, Gd₂d and M C. Gd₁d , Gd₂d , S and M D. M, Gd₁d , Gd₂d and S

Explanation

The correct sequence of the cell cycle is G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). In G1 phase, the cell grows and performs normal functions. During the S phase, DNA replication occurs. In G2 phase, the cell prepares for mitosis. Finally, in the M phase, the cell undergoes mitosis and divides into two daughter cells.

Which of the correct order of phases in prophsae I ?

A. Leptotene, diakinesis, pachytene, diplotene, zygotene B. Leptotene, zygotene, pachytene, diplotene, diakinesis C. Diakinesis, diplotene, pachytene, zygotene, leptotene D. Laptotene, pachytene, zygotene, diplotene, dikinesis

Explanation

Prophase I in meiosis is divided into five stages: leptotene, zygotene, pachytene, diplotene, and diakinesis. This order represents the progression of chromosomes through the initial stages of meiosis, where they condense, pair, exchange segments, and prepare for separation.

Prophase is characterized by :

A. spliting of centromere B. thread like appearance of chromosomes C. arrangement of chromosomes on metaphic plate D. pairing of homologous chromosome

Explanation

During prophase, the chromosomes become visible as thread-like structures due to condensation. This is one of the key characteristics of prophase, distinguishing it from other stages where chromosomes are either not visible or aligned differently.

Phase of cell cycle unique for DNA replication is :

A. S B. Gd₁d C. Gd₂d D. M

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

The S phase (Synthesis phase) of the cell cycle is unique for DNA replication. During this phase, the cell synthesizes a complete copy of the DNA in its nucleus, ensuring that both daughter cells will have identical genetic material.

At which stage of mitosis chromatids separate and passes to different poles :

A. Prophase B. Metaphase C. Anaphase D. Telophase

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Anaphase is the stage of mitosis during which chromatids separate and move towards opposite poles of the cell. This ensures that each daughter cell will receive an identical set of chromosomes.

● ● ● ● ●

Gd₂d phase is between :

A. end of mitosis and start of S phase B. end of S phase and start of mitosis C. start of S phase and start of mitosis D. end of S phase and end of mitosis

Post mitotic gap phase and synthesis phase of cell cycle are also respectively referred to as :

G₂and S

G₁and S

G₁ and G₂

S and G₂

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

The post-mitotic gap phase (G1) is the phase that occurs after mitosis and before the S phase, where the cell grows and prepares for DNA replication. The S phase is the synthesis phase where DNA is replicated.

● ● ● ● ●

The two chromatids of a metaphase chromosome represents :

A. homologous chromosome of a diploid set B. replicated chromosomes to be separated at anaphase C. non-homologous joined at the centromere D. maternal and paternal chromosomes joined at the centromere

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

During metaphase in mitosis, each chromosome consists of two sister chromatids that are identical copies of each other. These chromatids are replicated chromosomes that will be separated during anaphase, ensuring each daughter cell receives an identical set of chromosomes.

What is correct ?

A. DNA â€“ content become double during Gd₁d phase. B. Duration of interphase is short as compared to M â€“ phase C. Gd₂d â€“ phase follows mitotic phase. D. DNA â€“ replication occurs in S â€“ phase.

Explanation

DNA replication occurs during the S phase (Synthesis phase) of the cell cycle. This is the phase when the cell synthesizes a complete copy of the DNA in its nucleus, doubling the DNA content in preparation for mitosis.
