Exam 8: Molecular Biology and Transcription and Rna Processing

In intrinsic termination,inverted repeat DNA sequences followed immediately by a string of ________ produce an mRNA stem-loop followed by a string of ________.

A cell has a defect in polyadenylation.Which RNA transcripts would not be affected by this defect because they are not polyadenylated?

Describe the mechanism(s)used by bacteria and eukaryotes for transcription termination.

Spliceosome components are recruited to 3′ and 5′ splice sites by SR proteins bound to what DNA sequences?

Which three types of RNAs are found in both prokaryotes and eukaryotes?

Which type of mRNA is translated within a cell?

You want to design a drug that prevents transcription of mRNAs but does not affect transcription of other RNAs.What enzyme would you target?

Which assay allows you to identify the exact location of the protein-binding sequence within a promoter?

Name three functional RNAs unique to eukaryotes.

A gene has acquired a mutation in which the protein product has an "extra" 50 amino acids at the end.Which region of the gene was likely mutated?
