In this article we will discuss about the cell division and cell cycle in prokaryotes. Bacterial cell division is also termed as fission. The bacterial chromosome is circular and attached to the plasma membrane at a specific point. Its replication starts from an initiation point. Both the copies of the chromosome are attached to the plasma membrane, close to each [...]
In this article we will discuss about the chromosome movement during cell division. The chromosome movement during cell division is chiefly due to the spindle apparatus. This apparatus contains three different types of microtubules: (a) Astral microtubules, radiating from centrioles (found in animal cells only); (b) Continuous or inter-polar microtubules, passing from one pole to the other, account for the [...]
In this article we will discuss about the cell division in eukaryotes. Eukaryotic cell division involves two major events: (a) The division of nucleus into two daughter nuclei (karyokinesis), and (b) The division of cytoplasm to produce two daughter cells, each cell normally having a single daughter nucleus (cytokinesis). In eukaryotes there are two types of cell division, mitosis and [...]
