What is produced from double stranded, foreign RNAs to protect cells from infections.
What is RNA interference?
What is the specific process?
Small interfering RNAs.
It is the process by which the system is used to eliminate "foreign" RNA molecules- in particular, the double-stranded RNAs produced by many viruses and transposable genetic elements.
- 1. Double-stranded, foreign RNAs are cut into short fragments by a protein called Dicer.
- 2. The resulting double-stranded RNA fragments called small interfering RNAs are taken up by the same RISCs that carry miRNAs.
- 3. The RISC discards one strand of the siRNA duplex and uses the remaining single-stranded RNA to seek and destroy complementary foreign RNA molecules.
