For the most part it is through UDP, which is very insecure and that's one of the reasons why DNS attacks are so easy to pull off. If your really good at programming (or know somebody who is, like I did) you can get them to set you up with a new system which uses TCP. And the advantage of this is you can have any sort of encryption, 3/4/5 way handshake, intrusion detection etc...
If you want to learn about DNS, you should look into the UDP protocol first and get a good firm understanding. And alot of books when explaining UDP actually explain it with DNS.
