For RNA interference double stranded RNA required. How is dsRNA produced whether this mechanism ever takes place in human body

Hi Nihala,
For RNA interference ds-RNA is required which is an characteristic feature of Viral genomes.
Iam here with attaching an image hope it gives clear information to you.
No its does not takes place in human body.
Iit is induced to kill the viruses and other harmful gene processess.
During genetherapy process this phenomenon are used for correct/cure gene defects.
