DNS does not use port 56, unless you have something special.

The syntax is:
  access-list 110 permit tcp host <external server ip> host <global IP> eq 53
  access-list 110 permit udp host <external server ip> host <global IP> eq 53

You would have to post your complete config for me to be more specific for you.

Any time you chang the acl, you have to re-apply it to the interface:
   access-group 110 in interface outside

To check it, use "show access-list" and look for (hitcount= )
