Stages in proper sequence of prophase- I are

zygotene, leptotene, pachytene, diakinesis

leptotene, zygotene, pachytene, diplotene and diakinesis

eptotene, pachytene, zygotene, diakinesis and diplotene

diplotene, diakinesis, pachytene, zygotene and leptotene

B.

leptotene, zygotene, pachytene, diplotene and diakinesis

Prophase I is the longest phase of Meiosis. Recombination takes place or croosing over. It includes 5 sub- phases, which are as follows-

1. Leptotene

2. Zygotene

3. Pachytene

4. Diplotene

5. Diakinesis

The stage of cell cycle when cell has undergone differentiation is :

In cell cycle, during, which phase chromosomes are arranged in equatorial plate ?

Spindle fibres of mitotic cell are made up of

During meiosis crossing over occurs at

During meiosis crossing over occurs between which part of homologous chromosome ?

During mitosis nuclear membrane disappears at

In synapsis two homologous chromosomes are connected at

Which of the followings does not occur in the interphase of eukaryotic cell division?

Match the item in column I with those in column II and the choose the correct answer.

Column I	Column II
A. Mitosis	1. Occurs in diploid cells only
B. Meiosis	2. Occurs in both haploid and diploid cells
	3. Daughter and parent cells have same chromosome numbers
	4. Synapsis of homologous chromosomes.
