what is EcoRI in the chapter biotechnology?
Answers
EcoRI is a restriction endonuclease enzyme isolated from species E. coli. ... EcoRI is a restriction enzyme that cleaves DNA double helices into fragments at specific sites. It is also a part of the restriction modification system. In molecular biology it is used as a restriction enzyme.
EcoRI is a type II restriction endonucleases obtained from RI strain of Escherichia coli bacterium.
EcoRI contains a restriction system and modification system to kill the genetic material of the invader.
Restriction system:
Cuts the DNA strand anywhere along the length of the DNA and eventually killing the invader.
Modification system:
Helps the E.coli to modify its own DNA so that the endonucleases present in the invader will not affect E.coli.
Restriction system of EcoRI is used in genetic engineering.The DNA strands are cut at specific sites to give DNA strands with either blunt end or sticky end.
