To more accurately validate the predicted target genes of miRNAs and exactly determine the cleavage sites within the targets, an integrated strategy comprising RLM-RACE, Poly(A) Polymerase-Mediated (PPM)-RACE, and qRT-PCR was developed.

In plants, the perfect complementarity between most miRNAs and their targets enables the accurate predictions of their targets, while slicing of the targeted mRNAs facilitates target validation through RNA Ligase-Mediated (RLM)-Rapid Amplification of cDNA Ends (RACE) method.

Type I restriction endonucleases are complex endonucleases and have recognition sequences of about 15 bp;

#Unit 13. Methods in Biology

Type I restriction endonucleases cleave the DNA about 1000 bp away from the 5'-end of the sequence "TCA" located within the recognition site.

Type II restriction endonucleases are remarkably stable and induce cleavage either, in most cases, within or immediately outside their recognition sequences.
