What Evidence Would Suggest That Histone Acetylation Provides a Recognizable

Multiple Choice

What evidence would suggest that histone acetylation provides a recognizable surface to recruit proteins that bind to acetylated histones?

A) Mutation of a lysine in the tail of histone H3 in a promoter region to an alanine,which cannot be acetylated,prevents the binding of transcription factors that normally bind to that promoter.
B) Lysines interfere with the binding of transcription factors to histone H3K9.
C) Alanines bind to transcription factors very tightly.
D) Histone H3K9 cannot be acetylated and therefore does not bind transcription factors.
E) Acetylation of histone H3K9 inhibits binding of transcription factors.
