What is the process of copying the information in DNA to a molecule of mRNA?

Question

Quizplus · Accepted Answer

The process of copying the information in DNA to a molecule of mRNA is called transcription. During this process, RNA polymerase enzyme binds to a specific region on the DNA molecule and unwinds a small portion of the DNA double helix. One of the two strands serves as a template for the synthesis of a complementary mRNA molecule, which is assembled from nucleotides containing ribose sugar, uracil base, and phosphate group. The RNA polymerase adds nucleotides in a sequence complementary to the DNA template, elongating the mRNA molecule in the 5' to 3' direction. Transcription ends when the RNA polymerase reaches a termination signal on the DNA template, which causes the release of the mRNA molecule. The mRNA molecule then undergoes post-transcriptional modifications such as capping, splicing, and polyadenylation before it is ready to be translated into a protein.
