UV radiation is used to cause DNA breakage. UV reacts quickly hence helps to catch momentary protein binding and can be used in vivo as it penetrates cell membranes easily. But gels from such assays are difficult to interpret.

Induced pluripotent stem cell (iPSC) with the pluripotency of an embryonic stem cell. These genes were 

a. Sox2 and Oct4 (Oct3, Oct3/4, and Pou5f1) -which activated Nanog and other transcription factors that   established pluripotency and blocked differentiation

b. c-Myc which opened up chromatin and made the genes accessible to Sox2, Oct4, and Nanog

c. Klf4 -which prevents cell death
