what is a prophase? explan it?
Answers
Answer:
The first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.
Before prophase begins, the chromosomes duplicate to form two long, thin strands called chromatids. During prophase itself, the chromatids condense and thicken to form distinct bodies. ... For example, human beings have 23 pairs of chromosomes in all somatic cells, or 46 chromosomes in total.
Chromatin begins to condense and is visible in the form of chromosomes. Spindle fibres begin to form as well as centrioles. Prophase is important because this is when chromatin becomes chromosomes so the right number of chromosomes can be distributed equally to each daughter cell produced.

Answer:
Prophase is the first stage of cell division in both mitosis and meiosis. Beginning after interphase, DNA has already been replicated when the cell enters prophase. The main occurrences in prophase are the condensation of the chromatin and the disappearance of the nucleolus.
