RNA interference (RNAi) is a natural gene regulation process. RNAi technology offers potential for gene silencing therapeutics and controlling viral infections, showing promise for antiviral therapies.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • RNA interference (RNAi) is a conserved biological process in eukaryotes involved in gene regulation.
  • It plays a role in cellular defense, RNA surveillance, and developmental pathways.
  • RNAi mechanisms target and degrade specific RNA molecules based on sequence homology.

Purpose of the Study:

  • To explore RNA interference as a tool for functional genomics.
  • To evaluate RNAi technology for developing gene-silencing therapeutics.
  • To investigate the potential of RNAi in controlling viral infections.

Main Methods:

  • Utilizing sequence-specific targeting of RNA for gene regulation.
  • Employing short interfering (si) RNAs for gene inhibition.
