Question

the specific sequence of dna recognized by restriction endonuclease are

Answer 1

the restriction endonuclease act as a DNA scissors that cut DNA at a specific segment
and d-ligase help in binding of two dna

Answer 2

Restriction enzyme is a DNA cutting enzyme which recognizes specific sites on DNA strands. These specific sites on DNA strands are called Restriction Recognition sites. These sites contain specific (4-8 base pairs in length), sequence of nucleotides.

Restriction enzymes either produce sticky ends or blunt ends in a DNA molecule.
