DNA protected by a binding protein will leave a/an __________ where the binding protein comes in close proximity to DNA.

Question

Quizplus · Accepted Answer

A binding protein that protects DNA will leave a "footprint" where it comes in close proximity to the DNA. This footprint can be detected by a technique called DNase footprinting, which involves digesting the DNA with DNase I and then separating the fragments by gel electrophoresis. The regions of the DNA that are protected by the binding protein will be resistant to DNase cleavage and will appear as a band on the gel, creating a footprint pattern. Therefore, choice D is the correct answer.

DNA Protected by a Binding Protein Will Leave A/an __________
