Most(if not all routers) will act as a DNS proxy, where the PC uses the router as a DNS server and then the router passses the request on to the ISP(or whatever it's got set as it's DNS addreses. Whether your PC uses the routers DNS proxy depends on if you've got your primary DNS nameserver set to the IP of your router. This is true whether your IP is allocated by DHCP, or you have manually set a static address.

Even on a small home network you should always dns through your router as this can avoid un-necessary DNS lookups, for example I go to news.bbc.co.uk, the router has to pass the query on to external DNS resolution, my partner then goes to news.bbc.co.uk on her PC, this time the router answers the DNS request directly as it already knows the answer.
