Describe the formation of recombinant DNA by the action of EcoRI.
Restriction endonuclease recognizes a specific palindromic nucleotide sequence in the DNA.
The recognition site for EcoRI - 5' - G A A T T C - 3'
3' - C T T A A G - 5'
Restriction enzymes cut the strand of DNA a little away from the center of the palindromic sites, but between the same two bases on the opposite strands:
