WebFigure 6.3.2: Restriction Enzymes . Restriction enzymes hydrolyze covalent phosphodiester bonds of the DNA to leave either “sticky/cohesive” ends or “blunt” ends.This distinction in cutting is important because an EcoRI sticky end can be used to match up a piece of DNA cut with the same enzyme in order to glue or ligate them back together. WebRestriction Site Analysis (RFLPs) A restriction site is a sequence of approximately 6–8 base pairs of DNA that binds to a given restriction enzyme. These restriction enzymes, of which there are many, have been isolated from bacteria. Their natural function is to inactivate invading viruses by cleaving the viral DNA. WebThe restriction enzyme then makes a double-strand break in the invading DNA, making it accessible to cellular nucleases and therefore prone to degradation.
