WebJul 19, 2024 · Two processes occur in cell division: nuclear division or karyokinesis, and cytoplasmic division or cytokinesis. These two transformations can take place, one after the other, or independently, the first and the other after a while. However, for the nuclear division to take place, deoxyribonucleic acid (DNA) replication must first have taken place.

WebThe Prokaryotic Cell Cycle. The prokaryotic cell cycle is a regular pattern of growth, DNA replication, and cell division. Most prokaryotic cells begin to replicate, or copy, their DNA once they have grown to a certain size. When DNA replication is complete, the cells divide through a process known as binary fission.

WebThe ultimate objective is to divide the parent cell into daughter cells. ∙ Cytokinesis in animal cells occurs by furrowing of the cytoplasm. ∙ Furrow starts at the periphery and then moves inward, dividing the cell into two parts. ∙ In plant cells, cytokinesis is initiated with the formation of a cell plate in the middle of the cell.
WebMitosis is the process of cell division wherein the chromosomes replicate and get equally distributed into two daughter cells. The chromosome number in each daughter cell is equal to that in the parent cell, i.e., diploid. Hence, mitosis is known as equational division.
