Restriction bases are usually 4, 6 or 8 bases long. They recognise specific palindromic base sequences in DNA and are used to selectively cut DNA at sites known as 'restriction sites'. Different restriction nucleases are obtained and purified from different species of bacteria. These enzymes are made in bacteria to degrade viral DNA.
