This program was established in respect to the high levels of aging dams (greater than 11,000) esrablished across the nation from 1948 with a increasing amount that requires rehabilitation to keep up with the several importance they provide.

Dam Rehabilitation:

In this mechanism enzyme dicer cuts DSRNA into smaller fragments called SIRNA which form a complex with RISC in degrees specific

scZoUnD [109]

I believe the correct answer is mRNA. Dicer is a part of RNase III which leaves double stranded RNA and pre-microRNA into short double stranded RNA fragments called small interfering RNA and microRNA respectively. The Dicer facilitates the activation of RNA induced silencing complex (RISC), which are essential for RNA interference. The RISC has a catalytic component argonate, which is an endonuclease capable of degrading mRNA. siRNAs are specfic to the mRNA sequence unlike miRNAs which are not completely complementary to the mRNA sequence.
