WebMay 14, 2024 · DNA transcription of the genes for mRNA, rRNA, and tRNA produces large precursor molecules ( "primary transcripts") that must be processed within the nucleus to produce the functional molecules for export to the cytosol. Some of these processing steps are mediated by snRNAs. Web5.7 Summary. Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.

WebAn mRNA transcript is made by an enzyme called RNA polymerase II. As you can tell from the name, the function of RNA polymerase II is broadly similar to DNA polymerase. The only high-level difference is in the building blocks used. DNA polymerase uses a single strand of DNA as a template and synthesizes a strand of DNA.
