How Is The Pachytene Phase Of Prophase I Distinguished?

This phase is distinguished by the appearance of the recombination nodules.

They are complexes formed by a pair of synapse homologous chromosomes in the process of cell division.

In the zygotene phase of prophase I, chromosome synapsis is accompanied by the synaptonemal complex.

In the zygotene phase, synapsis occurs, and the paired chromosomes formed hence are referred to as homologous chromosomes.

In the zygotene phase, synapsis occurs.

In zygotene, chromosomes start to pair together, which is referred to as synapsis.

In this phase, chromosomes start to pair together in a process of synapsis.

On the basis of the chromosomal behavior, prophase I is subdivided into these phases – Leptotene, Zygotene, Pachytene, Diplotene and... View Article

At the end of meiosis II, four haploid cells are formed.

It is initiated after parental chromosomes replicate, producing identical sister chromatids at the S phase.

The process includes two sequential cycles of cell and nuclear division, however, there is only one cycle of DNA replication.

Mitotic division occurs in meristematic tissues – the lateral and apical cambium.

Cells must divide to restore the nucleo-cytoplasmic ratio.

Liquid endosperm in coconut is an example.

In some entities, karyokinesis is not followed by the process of cytokinesis, hence a multinucleate condition emerges which leads to... View Article

The nuclear envelope develops around the chromosome clusters at each pole forming two daughter nuclei.

At the beginning of telophase, chromosomes that have arrived at their corresponding poles decondense and lose their individuality.

Telophase is the last stage of karyokinesis.

Splitting of Centromeres and separation of chromatids.

Spindle fibres attach to kinetochores of chromosomes.
