Attachment of spindle fibers to kinetochores of chromosomes becomes evident in:

1.	Anaphase	2.	Telophase
3.	Prophase	4.	Metaphase

In a mitotic cycle, the correct sequence of phases is

1. S, ${\mathrm{G}}_1$, ${\mathrm{G}}_2$, M

2. ${\mathrm{G}}_1$, S, ${\mathrm{G}}_2$, M

3. M, ${\mathrm{G}}_1$, ${\mathrm{G}}_2$, S

4. ${\mathrm{G}}_1$, ${\mathrm{G}}_2$, S, M

During Meiosis 1, in which stage synapsis takes place?

Match the following events that occur in their respective phases of cell cycle and select the correct option:

Identify the meiotic stage in which the homologous chromosomes separate while the sister chromatids remain associated at their centromeres.
1. Metaphase-II
2. Anaphase-I
3. Anaphase-II
4. Metaphase-I

At metaphase, chromosomes are attached to the spindle fibres by their:

Centromere is required for:

What occurs in crossing over:

Crossing over that results in genetic recombination in higher organisms occurs between:

In the somatic cell cycle:
