What is the process of forming mRNA according to the information contained in the DNA molecule?

Explanation:
Transcription is the process of forming mRNA from a DNA template. During transcription, RNA polymerase binds to a promoter on the DNA, unwinds a small DNA segment, and uses one DNA strand as a template to synthesize a complementary RNA strand in the 5' to 3' direction. The RNA nucleotides pair with the DNA template (A with U, C with G, G with C, T with A), producing an mRNA molecule that carries the genetic information from DNA to the ribosome for protein synthesis. In eukaryotes, this initial mRNA is often modified — introns are removed and a 5' cap and a poly-A tail are added — before the mature mRNA exits the nucleus to be translated. Replication copies DNA to duplicate genetic material, not to make RNA; translation uses mRNA to build protein, not to form the RNA itself; translocation refers to movement along the mRNA or chromosomal rearrangements, not the creation of mRNA.
