RNA Interference
Über den Vortrag
Der Vortrag „RNA Interference“ von Kevin Ahern, PhD ist Bestandteil des Kurses „RNA and the Genetic Code“.
Quiz zum Vortrag
Which of the following is true regarding RNA interference?
- It relies on formation of duplex RNA sequences in cells.
- It occurs when the transcription of a gene is blocked.
- It involves the pairing of a target RNA to a complementary sequence by a protein called dicer.
- It arises when the RISC protein destroys an RNA duplex.
- RNA interference has a unique triple-stranded structure that leads to genetic silencing.
Which enzyme breaks the dsRNA in the RNAi pathway?
- Dicer
- RNAse
- DNAse
- Protease
- Ligase
Which of the following is not true regarding RNA interference?
- The siRNA contains a mismatched duplex with a bulge on it, whereas the miRNA represents a perfect duplex system.
- The presence of double-stranded RNA molecules in the eukaryotic cells stimulates the RNAi response.
- The RNAi response helps the cell to protect itself from the invader as well as to control its own gene expressions.
- The double-stranded viral RNA gets chopped off by an enzyme called dicer into silencing RNA molecules of 20 basepair lengths.
- Drosha and Dicer are two enzymes, which participate in the RNA interference process in the eukaryotic cells.
Which protein associates with the RISC complex and assists with target mRNA cleavage?
- Argonaute
- Dicer
- Drosha
- Drosha-dicer
- Lyase
