DNS uses a cascading approach for name resolution. With TCP, for every message, a connection setup is required. DNS requests and responses are generally very small, and fits well within one UDP segment. UDP is not reliable. In DNS, reliability is ensured at the application layer. After timeout, the DNS client sends back the requests.
