Question

in each image below, the dna antisense strand is on the top. which image shows the correct rna molecule being formed on the bottom?

Explanation:

Step1: Recall base - pairing rules

In transcription, DNA's antisense strand is used to make RNA. In RNA, uracil (U) replaces thymine (T). Adenine (A) in DNA pairs with uracil (U) in RNA, and cytosine (C) in DNA pairs with guanine (G) in RNA, and vice - versa.

Step2: Analyze each option

The first option has T in the RNA strand which is incorrect as RNA has U instead of T. The second option has non - standard bases in the RNA part. The third option has the correct base - pairing with U replacing T and correct complementary base - pairing (A - U, C - G) with the DNA antisense strand.

Answer:

The third image (with the RNA sequence UAGCU)
