Please explain RNA interference in detail-plz just don`t copy wat is in text

RNA interference means the involvement of small RNA molecules
with the regular transcription process.
During normal translation process m-RNA produces protein.
Some small inhibitory RNA (si-RNA) causes the inhibition of translation process, this is called as RNA interfrence.
here with attaching the image of it go through it.
Due to RNA intereference process the formatio of protein is inhibited.
This technology is useful to kill the growth of cancer cells,Viruses,growth of insect eggs etc.,
