What is RNAi?
RNAi is a small molecule of double-stranded RNA.
RNAi interferes with mRNA by binding to the mRNA molecule and breaking it down.
Interfering with mRNA prevents it from being translated into protein.
What is miRNA
A type of RNAi that is not fully complementary to the mRNA sequence.
What dowa miRNA do
miRNA can target multiple sequences of mRNA.
After miRNA has bound to mRNA, the mRNA is either degraded or stored for future use.
What is siRNA
siRNA is a type of RNAi that is complementary to the mRNA sequence it inhibits.
What does siRNA do
siRNA targets a specific sequence of mRNA.
After siRNA has bound to mRNA, the mRNA is broken down into smaller fragments.
The fragments of mRNA are degraded.
