Question

Which among the following processes are common for eukaryotic cell division and prokaryotic binary fission?

• A. DNA duplication, division of cell organelles, division of the cytoplasmic contents
• B. DNA duplication, mechanism of segregation of duplicated chromosomes, division of the cytoplasmic contents
• C. Formation of a septum, DNA duplication, division of the cytoplasmic contents
• D. Mechanism of segregation of duplicated chromosomes, formation of a septum, division of cell organelles

Answer 1

The correct option is C Formation of a septum, DNA duplication, division of the cytoplasmic contents

Statements "DNA duplication, division of cell organelles, division of the cytoplasmic contents" and "Mechanism of segregation of duplicated chromosomes, formation of a septum, division of cell organelles" are incorrect since binary fission only occurs in prokaryotes and prokaryotes do not have organelles.

Statement "DNA duplication, mechanism of segregation of duplicated chromosomes, division of the cytoplasmic contents" is also wrong since prokaryotes do not have a special mechanism of segregation of chromosomes as seen in mitosis.

Statement "Formation of a septum, DNA duplication, division of the cytoplasmic contents" is true since these processes take place in both binary fission as well as mitosis.
