Restricito enzymes cut the strand of DNA a little away from the centre of the palindromic site, but between the same two bases on the opposite single stranded strand, these overhanging stretches formed on each strand are called __________

Consider the following statements. A. Endonucleases remove nucleotides from the ends of the DNA whereas, exonucleases make cuts a specific positions within the DNA. Restriction enzymes cut the strand of DNA a little away from the centre of the palindrome sites. C.

Restriction endonuclease ( EcoRI) enzyme cut the strand of DNA

Assertion : Restriction enzymes cut the strand of DNA to produce sticky ends. Reason : Stickness of the ends facilitates the action of the enzyme DNA polymerase

Assetion: Restriction enzymes cut the strand 27 of DNA to produce sticky ends Reason : Stickiness of the ends faciliates the action of the enzyme DNA polymerase

Assertion: Restriction endonucleases produces overhanging stretches called stricky ends on each DNA strand Reason :Restriction enzymes cut the strand of DNA a little away from the centre of pallindrome sites

Assertion : Restriction enzymes cut the strand of DNA to produce sticky ends. Reason : In this process, there is net gain of twenty four molcules of ATP.

Restriction enzyme Eco RI cuts the DNA between bases G and A only when the sequence in DNA is
