In the animé TV series, the Digimon that are capable of DNA Digivolving (known as Jogress Shinka in Japan which translates to Jogress Evolution) are WarGreymon and MetalGarurumon which become Omnimon, ExVeemon and Stingmon which become Paildramon, Aquilamon and Gatomon which become Silphymon and Ankylomon and Angemon which become Shakkoumon.In Digimon Adventure V-Tamer 01, Devimon and Ogremon can DNA Digivolve to become SkullSatamon, Kuwagamon and Kokatorimon can DNA Digivolve to become Megadramon and Megadramon and Cherrymon can DNA Digivolve to become Ghoulmon.
You may need some requirements to DNA slide a Digimon but just go to the computer a Tamer Home,then use the Digilab Computer.Select a digimon you want to DNA slide and select its digimon partner.Choose DNA digivolve and you get a fused digimon
No, you cannot. I think that Digimon have to be at the same level (Champion, Ultimate, etc) to DNA Digivolve. However, if you have a DNA Digivolved digimon, get one of the digimon you digivolved it with (Like for Silphymon, Aquilamon or Gatomon) and if you DNA Digivolve, it should result in their rookie forms.
DNA evolution aka 'Jogress evolution' came from Digimon Adventure 02.

Digiconverting and armor and DNA digivolving
Depending on their stats certain Digimon can DNA digivolve to become new ones. There used to be a list somewhere but I don't know where it went... EDIT: I use the list from http://forums.supercheats.com/topic.php?topic=74877 which gives a full list of DNA Digivolutions AND an Armor Digivolution list.
