Question

Assertion :Binary fission is found in prokaryotes only. Reason: Binary fission in prokaryotes does involve the formation of spindle apparatus and chromosomal events.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

• The usual method of prokaryotic cell division is termed binary fission. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane.
• When the cell begins to pull apart, the replicate and original chromosomes are separated.
• The precise timing and formation of the mitotic spindle are critical to the success of eukaryotic cell division. Prokaryotic cells, on the other hand, do not undergo mitosis and therefore have no need for a mitotic spindle.

So the correct option is " Assertion is correct but Reason is incorrect ".
