Cell Cycle Meiosis I

Synapsis occurs between:

1.	a male and a female gamete
2.	mRNA and ribosomes
3.	spindle fibres and centromere
4.	two homologous chromosomes

During gamete formation, the enzyme recombinase participates during:
1. Metaphase-I
2. Anaphase-II
3. Prophase-I
4. Prophase-II

Given below is the representation of a certain event at a particular stage of a type of cell division. Which is this stage? 

1. Prophase-I during meiosis

2. Prophase-II during meiosis

3. Prophase of mitosis

4. Both prophase and metaphase of mitosis

The complex formed by a pair of synapsed homologous chromosomes is called:

1. Kinetochore

2. Bivalent

3. Axoneme

4. Equatorial plate

Arrange the following events of meiosis in a correct sequence:
I. Crossing over
II. Synapsis
III. Terminalisation of chiasmata
IV. Disappearance of nucleolus

1.	II, I, IV, III	2.	II, I, III, IV
3.	I, II, III, IV	4.	II, III, IV, I

During Meiosis 1, in which stage synapsis takes place?

1.	Pachytene	2.	Zygotene
3.	Diplotene	4.	Leptotene

Which stage of meiotic prophase shows terminalisation of chiasmata as its distincitve feature?

1. Diakinesis

2. Pachytene

3. Leptotene

4. Zygotene

The appearance of recombination nodules on homologous chromosomes during meiosis characterizes:
1. Terminalization
2. Synaptonemal complex
3. Bivalent
4. Sites at which crossing over occurs

Regarding Meiosis, which of the statement is incorrect ?

1.	Four haploid cells are formed at the end of Meiosis-II.
2.	There are two stages in Meiosis, Meiosis-I and II.
3.	DNA replication occurs in S phase of Meiosis-II.
4.	Pairing of homologous chromosomes and recombination occurs in Meiosis-I.

The process of appearance of recombination nodules occurs at which sub stage of prophase I in meiosis?

1.	Diakinesis	2.	Zygotene
3.	Pachytene	4.	Diplotene

Select the correct statements.

A.	Tetrad formation is seen during Leptotene.
B.	During Anaphase, the centromeres split and chromatids separate.
C.	Terminalization takes place during Pachytene.
D.	Nucleolus, Golgi complex and ER are reformed during Telophase.
E.	Crossing over takes place between sister chromatids of homologous chromosome.

Choose the correct answer from the options given below:

1.	B and E only	2.	A and C only
3.	B and D only	4.	A, C and E only

Given below are two statements:

Statement I:	Chromosomes become gradually visible under light microscope during leptotene stage.
Statement II:	The begining of diplotene stage is recognized by dissolution of synaptonemal complex.

In the light of the above statements, choose the correct answer from the option given below:
1. Both Statement I and Statement II are False
2. Statement I is True but Statement II is False
3. Statement I is False but Statement II is True
4. Both Statement I and Statement II are True

Match List-I with List-II:

	List-I (Sub Phase of Prophase I)		List-II (Specific characters)
A.	Diakinesis	I.	Synaptonemal complex formation
B.	Pachytene	II.	Completion of terminalisation of chiasmata
C.	Zygotene	III.	Chromosomes look like thin threads
D.	Leptotene	IV.	Appearance of recombination nodules

Choose the correct answer from the options given below:
1. A-I, B-II, C-IV, D-III
2. A-II, B-IV, C-I, D-III
3. A-IV, B-III, C-II, D-I
