Question

Chromatin remodeling enzyme complexes ______. Choose all that apply.

Group of answer choices:

1.cause DNA to be repositioned for access or tighter packing.

2.are non-histone proteins that can bind to the chromatin in interphase nucleus.

3.promote the transition from the 30nm fibre to the 11nm fibre.

4.are essential for regulating gene expression.

5.are able to bind to the chromatin structure anywhere and cause DNA within a nucleosome to be repositioned.

6.bind to chromatin by binding to chemical modifications in the histone tails.

Answer 1

According to me ,4rth one is correct answer because these protein complex binds on DNA ,wrapped around histone octamer and loose it or make it available to transcriptional machinery so that transcription of that region could be done . So they regulate gene expression .
