Which one of the following features differentiates G2
phase from G1 phase?
1. Synthesis of proteins.
2. 4C content of DNA.
3. 2C content of DNA.

When a cell is viewed under the microscope, it does
not show golgi complex, endoplasmic reticulum,
nucleolus, nuclear envelope in which stage of cell
division?
1. Early prophase
2. Late prophase
3. Interphase
4. Telophase
These given statements are related with specific phase
of meiosis, select the unrelated statement with the
phase given below.
Statement Phase
1. The homologous chromosome – Anaphase I
separate, while sister
chromatids remain associated
at their centromere
2. The bivalent chromosomes align – Metaphase I
on the equatorial plate
3. Cytokinesis follows resulting in – Telophase I
the formation of tetrad of cells
4. Terminalisation of chiasmata – Final stage
of prophase
During what phase in the cell cycle would you find the most DNA per cell?
1. G1
2. G2
3. S
4. Prophase II
“The synaptonemal complex is formed during _A_
stage and dissolves during _B_ stage”.
Complete the above statement by choosing the correct
option for A and B
A B
1. Diplotene Diakinesis
2. Leptotene Zygotene
3. Zygotene Diplotene
4. Pachytene Diplotene
Major event that occurs during anaphase of mitosis which brings about equal distribution of chromosomes is:
1. Condensation of chromatin
2. Replication of genetic material
3. Splitting of centromere
4. Pairing of homologous chromosomes
