Question

In transcription RNA polymerase uses one strand of DNA as a template to assemble nucleotides into a strand of RNA?

a. True
b. False

Answer 1

True, RNA polymerase uses one strand of DNA as a template to assemble nucleotides into a strand of RNA during transcription.

Step-by-step explanation:

During transcription, the DNA double helix partially unwinds to form a transcription bubble, allowing RNA polymerase to access the template strand. As RNA polymerase moves along this template strand, it catalyzes the addition of RNA nucleotides in the 5'→3' direction, building a new RNA strand that is complementary to the DNA template strand. Uracil (U) is incorporated into the RNA strand instead of thymine (T), pairing with adenine (A) on the DNA template.
