Restriction endonucleases are enzymes which
make cuts at specific positions within the DNA molecule
recognize a specific nucleotide sequence for binding of DNA ligase
restrict the action of the enzyme DNA polymerase
restrict the action of the enzyme DNA polymerase
A.
make cuts at specific positions within the DNA molecule
Restriction endonucleases recognise a specific DNA base sequence (recognition sequence of the recognition site, restriction sequence or restriction site) and cleave both the strands of DNA at or near the site. The enzyme cuts are DNA, generating restriction fragments wit overhanging ends or blunt ends.
