The complementary strand of mRNA to the DNA sequence TAGAAGTAG is ATCTTCATC.

Question

Quizplus · Accepted Answer

The complementary strand of mRNA to the given DNA sequence would be AUCUUACUC, not ATCTTCATC. The base pairs between DNA and RNA are T-A, A-U, C-G, and G-C, so in order to find the complementary mRNA strand, each base in the DNA sequence must be replaced with its corresponding RNA base. The correct process for transcription would give AUCUUACUC as the mRNA sequence.
