1.	Question : An intersting property of restriction enzymes is molecular cutting and past-ing. Restriction enzymes typically recognize a symmetrical sequenceof DNA . Notice that the top strand is the same as the bottom strand, but reads backward . When the enzyme cuts the strand between G and A, it leaves over-hanging chains a. What is this symmetrical sequence of DNA known as ?b. What is the significance of these overhanging chains ?c. Name the restriction enzyme that cuts the strand between G and A.
Answer» Solution :a. This symmetrical sequence of DNA is KNOWN as .palindromic se-quence . B. These overhanging chains have sticky ends and they can be easily joined by DNAligase. c. RESTRICTION ENDONUCLEASE from E.coli strain (Eco RI)
