Can someone explain to me the process of transcription in detail?

Question

Please I'm so lost any help in explaining the steps would be appreciated. This is for a college biology class and the exam is on Tuesday

Answer 1

Transcription happens when mRNA is formed as a copy of the gene.

1. Enzymes unwind and unzip the DNA in the area of the gene.
2. mRNA nucleotides match the unpaired bases of the gene. DNA's C to mRNA's G, G to C, T to A, and DNA's A to mRNA's U (uracil). That's the transcription part.
3. The newly formed mRNA strand separates from the gene and exits the nucleus through pores in the nuclear envelope.
4. The DNA is zipped back together and winds up again.

Answer 2

Transcription is the process by which a cell turns on a gene. It involves "unzipping" the DNA so that transcription enzymes (RNA polymerase) can copy the DNA into messenger RNA. This is done by activating the operon, removing any repressor proteins bound to the DNA that prevent transcription, or binding of an activator protein, choosing the correct side of the DNA to transcribe (there are two side but only one codes for the protein), the correct side is called the template strand. Actually copying the DNA into single strand messengerRNA (with uracil instead of thymine), this process occurs in the 5' to 3' direction, and transporting the mRNA into the cytoplasm for processing (removing introns) and translation.
