Question: What is the function of prophase 2?

What does prophase II mean?

Prophase II is the phase that follows after meiosis I, or after interkinesis if present. If interkinesis takes place, the nuclear envelope and the nucleolus disintegrate during prophase II. The chromosomes are condensed. The centrosomes replicate and move towards the opposite poles. … prophase.

What is the function of meiosis 2?

The second round of cell division is meiosis II, in which the goal is to separate sister chromatids. Prophase II: Starting cells are the haploid cells made in meiosis I.

What is the main function of prophase?

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

Why is metaphase 2 important?

Meiosis is a reproductive cell division since it gives rise to gametes. The resulting cells following meiosis contain half of the number of the chromosomes in the parent cell.

Does crossing over occur in prophase 2?

Crossing over does not occur during prophase II; it only occurs during prophase I. In prophase II, there are still two copies of each gene, but they are on sister chromatids within a single chromosome (rather than homologous chromosomes as in prophase I).

What happens during prophase I of meiosis?

During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.
