Question
Answer the following question:
Describe the formation of recombinant DNA by the action of EcoRI.
Advertisements
Solution
Restriction endonuclease enzyme EcoRl is used in molecular biology to cut the foreign DNA and vector DNA to form overhangs (called sticky ends). These sticky ends then form hydrogen bonds with their complementary counterparts. The segments with the help of DNA ligases are joined to produce recombinant DNA.
