Since, the question is incomplete the complete question is as follows:
Viruses with dsRNA genomes evolved a long time ago and can be found in parasitic relationships with species from a variety of taxa. What mechanism do eukaryotes use to combat such viruses?
Select all that apply.
RNA interference
posttranslational silencing
RNA-induced silencing
methylation of CpG islands
position effect variegation
genomic imprinting
Answer:
RNA interference
post translational silencing
RNA-induced silencing
Explanation:
Viruses are the pathogenic living organisms which invade the host cells of plants, animals, humans, and of other organisms to produce their own genetic material and progeny viruses. The following are the methods using which the eukaryotic organisms can prevent themselves from infections.
1. RNA interference: In this viral RNA is cleaved by the use of complementary RNA sequence present in the genome of the host cell.
2. Post translational silencing: In this the gene products of viruses are silenced.
3. RNA induced silencing: It involves the inhibition of replication of RNA of virus by the host cell machinery.
