The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins ... they carry out biochemical reactions just like enzymes ...

The oligonucleotide used to prime probe synthesis should be 20–25 nucleotides in length and complementary to the RNA strand to be analyzed. It should hybridize to the template DNA 250–500 ...

This protein can easily be programmed to find and bind to almost any desired target sequence, simply by giving it a piece of RNA to ... cuts the DNA at the target. When the cut is repaired ...
