introns - 2024 ACF Winter at UBC

Question

The U12-dependent “minor” type of these structures is flanked by AU-AC sites instead of the usual GU-AG sites. For 10 points each:

[10m] Name these structures that are excised by a ribonucleoprotein complex composed of snRNAs like U2. An alternative form of that process can produce protein isoforms.

ANSWER: introns

[10e] RNA splicing is largely absent from these single-celled organisms, whose lack of membrane-bound organelles differentiates them from eukaryotes.

ANSWER: prokaryotes [or prokaryotic organisms]

[10h] Introns are represented as arrow-studded thin lines between horizontal bars in these visualization tools. Popular examples of this type of software include IGV, Ensembl, and a namesake one hosted by UCSC.

ANSWER: genome browsers [accept Integrative Genome Viewer; accept Ensembl Genome Browser; accept UCSC Genome Browser]
