RNA polymerase that binds to the promoter to initiate transcription - chromatin must be … WebIn eukaryotes, a single gene will produce one gene product as all genes are regulated independently. This is in contrast to prokaryotes, which regulate genes in an operon structure where one mRNA may be polycistronic and encode for multiple protein products. Types of RNA polymerase
10.3: Prokaryotic Gene Regulation - Biology LibreTexts
WebThe structure of eukaryotic genes includes features not found in prokaryotes (Figure 1). Most of these relate to post-transcriptional modification of pre-mRNAs to pro-duce mature mRNA ready for translation into protein. Eukaryotic genes typically have more regulatory ele-ments to control gene expression compared to prokar-yotes.[5] WebJul 15, 2024 · Gene Structure Genes are encoded within long strands of DNA strands.
