Question

In transcription, which DNA strand has a sequence that is identical to the produced RNA (except RNA contains U and DNA contains T)?

o The sense strand
o The anitmatter strand
o The antisense strand
o The template strand

Answer 1

In transcription, the sense strand of DNA has a sequence identical to the produced RNA, with the exception that RNA contains uracil in place of thymine.

Step-by-step explanation:

In the process of transcription, the DNA strand that has a sequence similar to the produced RNA is the coding strand, also referred to as the sense strand. This is because, during transcription, the enzyme RNA polymerase synthesizes RNA using the antisense strand (template strand) as a template. As a result, the RNA molecule is actually complementary to the antisense strand and thus, except for the replacement of thymine (T) with uracil (U), it is identical in sequence to the sense strand.

To clarify, the antisense strand serves as the template, meaning the RNA polymerase reads this strand and creates an mRNA sequence that is complementary to the antisense strand and identical to the sense strand, bar the T replaced by U.

The RNA sequence is identical to the sense strand of DNA (also known as the non-template or coding strand), with the only difference being that RNA contains uracil (U) in place of thymine (T).
