Question

What happens in prophase 1 of meiosis?

Answer 1

Mitosis is the separation mechanism between two identical daughter cells of the genetic material carried in the core of a parent cell. Prophase is the first phase of mitosis. During prophase, chromatin, a complex of DNA and proteins found in the nucleus, condenses.

Complete answer:
During prophase I, mitotic differences begin to emerge. In meiosis I, the chromosomes begin to pair up, just as they do in mitosis. Every chromosome carefully aligns with its homologue partner so that the two coordinates are in the same place along their entire length.
The process of homologous chromosomes exchanging parts begins. The synaptonemal complex, a protein structure that holds the homologous together, aids in this process. All the way through development and the exchange of hereditary material, the chromosomes would be stacked one on top of the other.
Each homologous chromosome aligns with itself to form quadruplicates. While the chromosomes are being arranged, parts of them may be traded or exchanged. This cycle is important because it encourages hereditary variation.
Centrosomes migrate to the cell's inverse shafts and axle contraption structure as Prophase 1 progresses.

Note:
In diploid cells, one set of homologous chromosomes (or homologs) comes from the father, while the other comes from the mother. This is known as a 2n arrangement, or two homologous chromosomes. For logical messages, 2n = 46 is a common length. This refers to the 23 distinct human chromosome structures. In graphs where a complete arrangement of chromosomes does not fit, they may state 2n = 4 or 2n = 8.
