Congression is a phenomenon
Answers
Answer:
Chromosome congression truly represents the first challenge of mitosis and culminates with the formation of a metaphase plate, a hallmark of mitosis in metazoans, and occurs in tight spatiotemporal coordination with the assembly of the mitotic spindle that mediates the microtubule-chromosome interactions required for ..
Chromosomes at the metaphase plate
Explanation:
The chromosomes align on the metaphase plate in the center of the cell during metaphase, a stage of eukaryotic cell division.
- Sister chromatids are migrating to the poles.
The sister chromatids of each chromosome separate and travel to opposing poles of the cell during Metaphase, which leads to Anaphase. The kinetochore microtubules shrink and pull the chromosomes toward the spindle poles during the initial stage of anaphase, which is also known as anaphase A.
- Homologous chromosomal pairing
Synapsis is the close pairing of homologous chromosomes. During meiosis, the pairing of two chromosomes is known as synapsis. It permits homologous couples to be matched up prior to segregation, allowing for possible chromosomal crossing. During prophase I of meiosis, synapsis occurs.
- Pairing chromosomes are separated.
Homologous chromosomes are chromosomes that are separated by their pairs. Diplotene is the first step of homologous chromosomes. The synaptonemal complex begins to dissolve at this phase. At crossing points, the bivalents' recombined homologous chromosomes split from one another. The second stage of meiosis is zygotene.
