About the Lecture
The lecture RNA Splicing by Kevin Ahern, PhD is from the course RNA and the Genetic Code.
Included Quiz Questions
Which of the following statements about splicing is not true?
- It is almost exclusively found in prokaryotic cells.
- It involves the removal of intervening sequences called introns from an RNA.
- It involves the joining together of sequences called exons that are separated by introns.
- It creates lariat structures in the excised introns.
- It affects mRNA, rRNA, and tRNA.
What is the unusual phosphodiester bond linkage within a lariat structure?
- 2’ to 5’ bond
- 2’ to 3’ bond
- 3’ to 5’ bond
- 3’ to 1’ bond
- 1’ to 5’ bond
Which statement is true regarding the RNA splicing process?
- The removal of introns prodcues a lariat structure.
- During self-splicing of pre-mRNA, the exons get joined to each other in a lariat structure form, whereas the intron gets released as a linear molecule.
- Splicing occurs almost exclusively in prokaryotes.
- The process of splicing includes the excision of the intervening section of RNA, called exons, and joining of the end of RNA which were removed, called introns.
- The spliceosome is composed of snRNAs and DNA.
