A scientist has discovered a new gene that she believes encodes a transcriptional activator protein. She is trying to determine where this protein binds. Which of the following describes a technique she could use to answer her question?
A) Chromatin immunoprecipitation to determine the DNA sequences to which the putative transcriptional activator protein binds
B) RNA interference to determine the RNA sequences to which the putative transcriptional activator protein binds
C) Crosslinking to determine the interactions the putative transcriptional activator protein has with other proteins
D) Chromative immunoprecipitation to determine the proteins to which the putative transcriptional activator protein binds
E) RNA interference combined with crosslinking to determine all DNA and RNA sequences to which the putative transcriptional activator protein binds

Chromatin immunoprecipitation is a technique used to determine the DNA sequences to which a protein binds. In this case, the protein of interest is a putative transcriptional activator protein, and the scientist is trying to determine where it binds in order to understand its function.
