question 65

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.
