Title: What defines the end of a eukaryotic gene? Post by: krakrakels on Jan 4, 2022 What defines the end of a eukaryotic gene?
▸ A 3' UTR of at least 25 nucleotides recruits an RNase that cleaves the pre-mRNA. ▸ There is no clearly defined end to eukaryotic genes, unlike for bacterial genes. ▸ A stem-loop structure in the transcriptional terminator region stalls the RNA polymerase. ▸ Presence of a stop codon leads to RNA polymerase stalling and ceasing transcription. ▸ Presence of a polyadenylation signal sequence leads to cleavage of the pre-mRNA.
