Process of mRNA Production

1. Initiation: RNA polymerase binds to the promoter region of a gene on the DNA template in the nucleus. 2. Elongation: RNA polymerase moves along the DNA strand, unwinding it and adding complementary RNA nucleotides (A, U, G, C) to the growing mRNA strand. 3. Termination: Transcription concludes as RNA polymerase reaches the terminator sequence, causing mRNA and RNA polymerase to detach from the DNA template. 4. mRNA Processing: In eukaryotes, pre-mRNA undergoes modification, including capping at the 5' end and addition of a poly-A tail at the 3' end, along with removal of introns by splicing. 5. Export: Processed mRNA exits the nucleus and enters the cytoplasm.
