Transcription involves rewriting genetic information from DNA to mRNA, with RNA polymerase playing a crucial role. In eukaryotic cells, DNA to mRNA transcription occurs within the nucleus, producing pre-mRNA.
The genetic code links groups of nucleotides in an mRNA to amino acids in a protein. Start codons, stop codons, reading frame.

The process of mRNA translation differs between prokaryotes and eukaryotes. Prokaryotic mRNA has a Shine-Dalgarno sequence for ribosome binding, while eukaryotic mRNA has a 5' cap and poly-A tail for protection and ribosome binding.
