Anaphase

Q.

What is the longest phase of mitosis?

Q. Condensation of chromatin and decondensation of chromosomes occur respectively during

1. telophase and prophase
2. prophase and telophase
3. telophase and metaphase
4. prophase and anaphase

Q. Which of the following is not related to anaphase?

1. Splitting of centromere
2. Separation of chromatids
3. Attachment of spindle fibres to chromosomes
4. Chromosomes assuming shapes of v, l, j, i

Q. Which phase would have occurred before the phase shown in the image?

1. Anaphase
2. Metaphase
3. Telophase
4. Prophase

Q. Which stages of cell division do the following figures A and B represent, respectively?

1. Metaphase - Telophase
2. Telophase - Metaphase
3. Late Anaphase - Prophase
4. Prophase - Anaphase

Q. Sister chromatids separate during

1. metaphase
2. prophase
3. anaphase
4. telophase

Q. Q what is the difference between metaphase of mitosis and metaphase 2 of meiosis 2.

Q.

In meiosis, bivalents are formed during

1. Diakinesis

2. Metaphase-I

3. Metaphase-II

4. Zygotene

Q. Which fibres are required during anaphase to move chromosomes from equator to the poles?

1. Chromosomal fibre
2. Interzonal fibre
3. Both a and b
4. Any protein fibre

Q. Which among the following events does not occur in pre-mitotic phase of interphase?

Q. Identify the phase of mitosis and structure labelled as X in the image given below.

1. Metaphase, spindle fibre
2. Metaphase, centriole
3. Prophase, centriole
4. Anaphase, centriole

Q.

Match the stages of mitosis listed in column I with the important events pertaining to respective stages given under column II; and choose the answer which gives the correct combination of alphabets of the two columns:

$\begin{array}{cccc}& ColumnIStagesofmitosis& & ColumnIIImportantevents\\ A& Interphase& p& Equatorialplateformation\\ B& Metaphase& q& Daughterchromosomesmovetooppositepoles\\ C& Anaphase& r& Centriolesdivde\\ & & s& Syntheticphase\end{array}$

1. A = s, B = p, C = q

2. A = s, B = q, C = p

3. A = s, B = r, C = p

4. A = r, B = s, C = p

Q. Phase of shortest duration is

1. Prophase
2. Metaphase
3. Anaphase
4. S-phase

Q. Which among the following events does not occur in the anaphase of cell cycle?

Q.

Which one of the following is the shortest of all stages in mitosis?

1. Prophase

2. Interphase

3. Metaphase

4. Anaphase
