Both unicellular and multicellular organisms undergo mitosis. What are the differences, if any, observed in the process between the two?
Ans.
In unicellular organisms, the cells are divided into two parts. This type of cell division is called amitosis. In multicellular organisms, karyokinesis takes place before the division of cytoplasm. In amitosis, duplication of DNA content takes place simultaneously with the division of the nucleus. In the case of multicellular organisms, there is a separate S phase for duplication of DNA.
