Which of the following statements is NOT true of mitosis?

1.	A single nucleus gives rise to two identical daughter nuclei.
2.	The daughter nuclei are genetically identical to the parent nucleus.
3.	The centromeres divide at the onset of anaphase.
4.	Homologous chromosomes synapse in prophase.

In oocytes, the diplotene can last for months or years, since at this stage:
1. DNA proof reading and excision repair is performed
2. The proteins for metabolism are re-formed
3. The chromosomes condense and engage in RNA synthesis
4. The cell is temporarily withdrawn from the cell cycle

A ribbon-like structure consisting of three protein components and extending across the region of synapsed chromosomes during the prophase of meiosis, is called:

The point of contact between paired chromatids during meiosis, resulting in a cross-shaped configuration and representing the cytological manifestation of crossing over is called:

Organisms prefer sexual mode of reproduction in adverse conditions because:

If there were 4 chromosomes present during prophase I, how many chromosomes are there in each cell at the end of anaphase II?
1. 2
2. 4
3. 8
4. 16

Which of the following distinguishes the prophase I of meiosis from the prophase of mitosis?
1. homologous chromosomes pair up
2. spindle forms
3. nuclear membrane breaks down
4. chromosomes become visible

With respect to meiosis, when does DNA replication occur?

The phase of mitosis in which the spindle fibers break apart, two new nuclear membranes begin to form, and the chromosomes disperse into chromatin is

The most important significance of meiosis is that:
