One fundamental difference between transcription in prokaryotes and eukaryotes is: eukaryotic RNA transcripts undergo polyadenylation (poly-A tail; cap) eukaryotes produce single RNA transcripts called operons that code for several proteins prokaryotes undergo capping of their 5' end of the RNA transcript prokayotic transcription occurs in the nucleus O prokaryotes have intervening sequences that are spliced during processing of the RNA transcript
Why do promoter mutations cluster at positions −10and −35 as shown in Figure 11-11? Which protein-DNAinteraction is disrupted by these mutations?
SR proteins are essential to proper spliceosome assembly and are known to take part in the regulation of alternative splicing. Surprisingly, the role of SR proteins in splice-site selection and alternative splicing is affected by the promoter used for the transcription of the pre-mRNA. For example, through genetic engineering, RNA polymerase II promoters that have somewhat different sequences can be created. When pre-mRNAs with exactly the same sequences are transcribed from two different RNA polymerase II promoters that differ slightly in sequence, which promoter is used can affect how the pre-mRNA is spliced. Propose a mechanism by which the DNA sequence of an RNA polymerase II promoter could affect alternative splicing of pre-mRNA.
The diagram, shown in attatched image, shows an mRNA that is alternatively spliced. The alternatively spliced variant contains Exon 1, Exon 2, and Exon 4. Indicate below if a splice site is used, blocked by a modifying protein such that the spliceosome must choose a different site, or skipped to make this alternatively spliced variant.
