Solution and Explanation
(a)
Restriction enzyme: EcoRI.
The sequences are referred to as palindromic sequences.
(b)
The arrows indicate the site where the restriction enzyme EcoRI cuts the DNA.
Result: The DNA is cleaved into fragments with sticky ends, enabling the insertion of foreign DNA during genetic engineering.
