The figures below shows 3 phases of mitosis select the option given correct identification together with the correct event ?
1. C- Telophase-Nuclear envelope assembles around the chromosome clusters
2. B- Anaphase-Segregation of homologous chromosomes.
3. A- Prophase-Chromosomes get fully condensed.

At anaphase-II, sister chromatids move towards opposite poles of the cell by :
1. Contraction in spindle fibre attached to kinetochores
2. Shorterning of microtubules attached to kinetochores
3. Lengthening of microtubules attached to kinetochores
4. Relaxation in spindle fibre attached to kinetochores
Following are the events occurs during meiosis :
(A) Appearance of chiasmata
(B) Synapsis
(C) Assembly of meiotic spindle
(D) Use of recombinase enzyme
