In its more common "B" form, its 22-angstrom major grooves can be accessed by transcription factors.
Xeroderma pigmentosum is a disorder in which UV-induced dimers of one component of this substance cannot be repaired. The "Z" form of this substance is more often found when it undergoes negative supercoiling, and also when it undergoes a process which begins at its TATA box. In its more common "B" form, its 22-angstrom major grooves can be accessed by transcription factors. This polymer is composed of a phosphate, a pentose sugar, and a purine or pyrimidine nitrogenous base such as thymine. For 10 points, name this nucleic acid which encodes the genetic information of all eukaryotes.
