Which of the followings does not occur in the interphase of eukaryotic cell division?
Increase of ATP synthesis
Increase of DNA synthesis
Increase of RNA synthesis
Reduction in cell size
D.
Reduction in cell size
Interphase is the living phase of the cell. Here, cell spends its majority of time and prepares itself for cell division. This increases its size and makes a copy of its DNA. Majority of eukaryotic cells spends most of their time in interphase.
In synapsis two homologous chromosomes are connected at
centromeres
chromomeres
telomeres
none of these
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
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. |
A- 1; B- 2
A- 2; B- 3
A- 3; B- 4
A- 4; B- 1
