Answer 1

First of all you need to understand that the names of restriction enzymes are derived from the bacterial name where the enzyme is extracted/produced/discovered.

ie. EcoR1 = E. coli

AvaII - Anabaena variabilis

Recognition site:

5'-G^G A C C-3'

3'-C C T G^G-5'

DpnII - Streptococcus pneumoniae

5'-N^GATCN-3'

3'-NCTAG^N-5'
