Assertion & Reason +4 −1

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).

Assertion (A) : Euchromatin is less condensed DNA than heterochromatin DNA.

Reason (R) : Euchromatin is transcriptionally active DNA thus needs to provide the access to transcription machinery.

In light of the above statements, choose the correct answer from the options given below.

Both (A) and (R) are true and (R) is the correct explanation of (A) Both (A) and (R) are true but (R) is NOT the correct explanation of (A). (A) is true but (R) is false (A) is false but (R) is true.
