Final answer:
Transcription occurs on the template strand of DNA, with RNA polymerase moving in the 3' to 5' direction and synthesizing a complementary RNA strand.
Step-by-step explanation:
The transcription process occurs on the template strand of DNA. In transcription, RNA polymerase moves along the template strand in the 3′ to 5′ direction, synthesizing an RNA strand that is complementary to the template strand. The resulting mRNA sequence is the same as the non-template strand, but with uracil (U) replacing thymine (T).
The bottom strand of DNA serves as the template strand during transcription, and RNA polymerase reads this strand in the 3' to 5' direction to synthesize mRNA in the 5' to 3' direction.
The process of transcription involves the enzyme RNA polymerase using one of the DNA strands as a template to synthesize messenger RNA (mRNA). During this process, the RNA polymerase reads the template strand in the 3' to 5' direction, which allows the formation of the mRNA strand in the complementary 5' to 3' direction. Therefore, the correct description of how transcription occurs is that the bottom DNA strand acts as the template strand, and the RNA polymerase moves along this strand from 3′ to 5′, creating the RNA in the 5′ to 3′ direction. As it synthesizes the mRNA, the bases are paired according to the rules of Watson-Crick base pairing, with uracil (U) being incorporated in place of thymine (T). The transcription process occurs on the template strand of DNA. In transcription, RNA polymerase moves along the template strand in the 3′ to 5′ direction, synthesizing an RNA strand that is complementary to the template strand. The resulting mRNA sequence is the same as the non-template strand, but with uracil (U) replacing thymine (T).
