I have a Nexus 7000 Core Switch , and i need to allow the domain controller ip 10.x.x.x for DHCP relay on switch.

You need something like this:
interface Vlan20
ip dhcp relay address 10.1.1.1

1st. what broadcast packets and which protocols do you want to forward via ip helper-address command ?
2nd. Exemple: In case of dhcp, if dhcp server is on the same LAN with the clients you don't need to use ip helper-address because the broadcast packets will be received also by the dhcp server which will do his job.. If the dhcp server is outside the LAN with the clients than you need ip help-address command.

The DHCP can be installed on a server as part of the AD and can also be located at the central location. As long as the DHCP server is routed and reachable by the remote hosts, than they can obtain an IP address from it. So, although it nice to have a local DHCP at each location, but it is not necessary.
