What type of enzyme is used to cleave DNA?

restriction endonuclease
restriction enzyme, also called restriction endonuclease, a protein produced by bacteria that cleaves DNA at specific sites along the molecule. In the bacterial cell, restriction enzymes cleave foreign DNA, thus eliminating infecting organisms.

Can a restriction enzyme have multiple cut sites?

The standard Type II restriction enzymes, such as EcoRV and BamHI, are homodimers that recognise palindromic sequences, typically 4–8 bp long, and cut both strands at specified positions within the sequence. They cleave DNA with multiple sites by means of separate reactions at each site.

Which restriction enzyme forms blunt ends?

Other restriction endonucleases produce “blunt end” in which there are no unpaired bases or overhangs in the end of the fragments. These pieces of DNA can not anneal to each other and hence are more difficult to clone.

What does fidelity mean in biology?

The property of an amino-acid-activating enzyme or a polymerase to correctly charge a tRNA or to correctly place a residue in a growing polypeptide or polynucleotide.

How does a multi-enzyme system work?

The product formed from each reaction is liberated and is acted upon by another enzyme of the sequence. Some of the multi-enzyme systems may operate in a different way, when the enzymes are closely associated with each other to form a multi-enzyme complex. The fatty acid synthetase of yeast provides an example of a multi-enzyme complex.

Why do lignocelluloses produce multienzyme xylanases?

The production of a multienzyme system of xylanases, in which each enzyme has a special function, is one strategy for microorganisms to achieve effective hydrolysis of xylan. Most of the fungi-degrading lignocelluloses produce functionally diverse hemicellulases with many isoforms ( Badhan et al., 2004; Wong et al., 1988 ).
