Double-stranded RNA, or dsRNA, is a double-helical structure made consisting of two complementary strands of RNA. It is created in huge amounts during viral replication cycles or serves as the genetic material of dsRNA viruses, which are strongly linked to the majority of viral infections. Because almost all species can recognize and react to dsRNA, it is essential for immunological control. DsRNA replicates inside host cells to produce new mRNA and DsRNA genomes. Viral proteins are created from the resulting single-stranded mRNA by host ribosomes, and these proteins combine with fresh genomes to form viral particles that are then released to infect the next cell.

A crucial genetic mechanism called RNA interference (RNAi) is mediated in large part by dsRNA. An enzyme known as Dicer recognizes long double-strand breaks (dsRNA) upon entry into cells and cleaves it into small interfering RNA (siRNA) or precursor microRNA (pre-miRNA) fragments, each of which is roughly 20 nucleotides long. The RNA-induced silencing complex is created when these fragments attach to proteins (RISC). One strand of the RNA duplex guides RISC to bind complementary target mRNA when it splits within RISC. This binding stops ribosome binding or causes mRNA breakdown, which stops protein translation and inhibits the expression of particular genes. The development of gene therapies, studies on gene function, and research on antivirals all depend on this process of gene silence.

The current dsRNA's potential applications in the agricultural sector are being extensively researched. Using the RNAi mechanism, dsRNA can be introduced into genetically modified (GM) crops to silence target genes, improving crop attributes and strengthening pest and disease defenses. Furthermore, dsRNA has been proven to degrade quickly, with a half-life of less than three days, and does not survive in aquatic systems, making it ideal for foliar spraying on plant surfaces. Because of its ability to enter insect cells quickly by oral intake and its precise specificity, dsRNA is a viable alternative to traditional insecticides for pest management that is effective, non-toxic, and sustainable. However, constraints such as nuclease degradation and absorption efficiency continue to pose hurdles to ensuring adequate delivery.
