Question

how does ecor1 specifically act on dna molecule

Answer 1

Answer:

by recognising the specific dna sequence it binds to that site and starts the process of cutting dna

Answer 2

EcoRI is a restriction enzyme that cleaves DNA double helices into fragments at specific sites. ... The / in the sequence indicates which phosphodiester bond the enzyme will break in the DNA molecule. Other restriction enzymes, depending on their cut sites, can also leave 3' overhangs or blunt ends with no overhangs.
