It is generally assumed off screen, though never stated directly in the TV show, that a Time Lord's regenerational ability is linked to the "Rassilon Imprimatur" - a third strand of DNA that links a Time Lord to his or her TARDIS and allows their bodies to stand up to the molecular stresses of time travel.
Time Lords regenerate because they have a injury or something is wrong, it's their way of healing themselves.
The standard number of regeneration cycles for a time lord is limited to 12 times (meaning 13 bodies). However it is possible for Time Lords to be granted extra regenerations. There is evidence the regeneration limit was something externally imposed by the Time Lords, and therefore may not exist anymore now that Gallifrey is gone.
The eighth Doctor regenerated offscreen and nothing is known about how or why he regenerated. The eighth Doctor appeared onscreen only once in a TV movie. We know th Time War happened between the TV movie and the start of the 2005 series. It's widely assumed that whatever the Doctor did to end the Time War caused him to regenerate.
A Timelord can regenerate 12 times and have 13 bodies, the 13th time instead of regenerating he is supposed to die.
The tenth doctor regenerated because he absorbed all the radiation from a radiation chamber to save Wilf's (Donna Noble's grandfather's) life. Wilf knocked four times, so the Doctor knew it was time for him to die (because in effect the tenth doctor dies and the eleventh doctor is born). Episode: The End of Time (part 2) I know this all true but actually the doctor was a little bit scared of what will happen to him when he regenerates for the tenth time because he absorbed all the radiation in order to save dona's grandfather so noble family won't respect him as a enemy. The doctor was friendly but angry at the time but wanted to filled the prophecy so he knocked four times. ] first time : stop the master plan to take over the universe second time : help donna's grandfather third time : visited all companions even know he injured from radition four time : successfully regenerated into his eleventh incarnation with a few injuries but did as wuz predicted
Time Lords regenerate because they have a injury or something is wrong, it's their way of healing themselves.
NuWho -- Episode name : Utopua/The Sound of Drums/Last of the Time Lords. This is when we see Derek Jacobi regenerate into John Simm
The current doctor (the tenth) will regenerate in the final special of 2009. Other than that there have been loads (old age, exile by Time Lords, radiation from cave, falling off radio telescope, etc ....
No. He disappears into the time war portal with the Time Lords.
Time Lords get 12 regenerations, meaning 13 incarnations in total, though The Master has had more than this, by various means.
Because the astronaut shot him whilst he was regenerating. A Time Lord can be killed out right if they are between regenerations. This shows us that even Time Lords are not invincible.
In the movie, The End Of Time.
Romana was another Time Lord, like the Doctor.
Romana (or, in full, Romanadvoratrelundar) was a Time Lady, and so, like all Time Lords and Ladies (such as the Doctor), could regenerate. She does so at the beginning of 1979's Destiny of the Daleks.Presumably the Doctor's grand-daughter, Susan, could also, but this was never discussed on screen.
Are you referring to a rating system? Or maybe his 12th regeneration? If you are referring to the ladder, the reason Time Lords can regenerate 12 times is because after they pass The Time Academy, they receive a 12 count regeneration cycle and a Tardis.

If you mean how did the second turn into the third, then he was punished by the time lords, they forced him to re-generate and banished him to earth. If you mean the third into the forth, he was "wounded" by radiation while fighting the spider queen, after he returns to earth he collapses and is helped by a fellow time lord to regerate.
