Vedclass · Answer

(A) During the interphase of the cell cycle,the cell is metabolically active and prepares for division. The genetic material exists in the form of a loose,thread-like network known as chromatin. Because these fibers are highly extended and dispersed throughout the nucleus,individual chromosomes cannot be distinguished under a light microscope. Chromosomes only become visible as distinct,condensed structures during the $M$-phase (mitosis or meiosis). Therefore,both the assertion and the reason are correct,and the reason provides the correct explanation for the assertion.

$S -$ Assertion: Individual chromosomes are not identifiable during interphase.
$R -$ Reason: They exist as highly extended and elaborate nucleoprotein fibers called chromatin.
