Quiz zum Vortrag
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.
