shRNA | siRNA | RNAi
shRNA and siRNA molecules are synthetic RNA molecules that are designed to specifically target and degrade messenger RNA (mRNA) molecules, which are responsible for the expression of genes. shRNAs are typically expressed from plasmid vectors, which are circular pieces of DNA that can be manipulated and propagated in bacterial cells. Once inside a cell, the shRNA is transcribed into a hairpin-shaped RNA molecule, which is then processed by cellular enzymes into siRNAs that can specifically recognize and bind to target mRNA molecules.
The use of shRNA and siRNA as cloning vectors has several advantages over traditional methods of gene expression and knockdown. First, shRNA and siRNA can be used to study gene function in a highly specific manner, allowing researchers to investigate the roles of individual genes in complex biological processes. Second, shRNA and siRNA can be used to silence genes in a reversible and tunable manner, making them useful tools for studying dynamic processes such as development and disease progression. Finally, shRNA and siRNA can be used in a wide range of organisms, from bacteria to plants to animals, making them highly versatile tools for biological research.
