Question

Assertion :Template or antisense strand, having 3 \\ 5 polarity takes part in transcription. Reason: Non-template or sense strand, having 5 \\ 3 polarity, does not take part in transcription.
  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Both Assertion and Reason are incorrect

B
Assertion is correct but Reason is incorrect
C
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
D
Both Assertion and Reason are incorrect
Solution
Verified by Toppr

Strand of DNA which has 3 → 5 polarity is called template strand or master strand or antisense, or (-) strand. The other strand which has a polarity of 5 → 3 is displaced during transcription. This non-template strand which does not take part in transcription is also called sense or coding strand or plus (+) strand because genetic code present in this strand is similar to genetic code (based on mRNA) except that uracil is replaced by thymine.
So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
