In eukaryotic transcription what is the function of a chromatin remodeling complex? Chromatin remodeling complexes form nucleosome structures at protein-coding regions to lock genes from transcription when they are inactive. Chromatin remodeling complexes clear nucleosomes away from enhancer regions, so that transcription goes at full rate. Chromatin remodeling complexes reform DNA structure after transcription is complete to keep it stable . Chromatin remodeling complexes clear nucleosomes away from promoter regions, so that transcription initiation complexes can form and function.

which if the following best describes the mechanism by which chromatin remodeling complexes loosen the dna wrapped around the core histones A) they chemical lie modify the DNa changing the affinity between the histones octaves and the DNA B) they use energy derived from ATP hydrolysis to change the relative position of the Dan and the core histone octamer C) they remove histone H1 from the linker DNA adjacent to the core histone octamer

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...

i need help with 10 and 11 please
The extent of condensation of chromatin plays an important role in the regulation of RNA transcription in eukaryotic cells. Chromatin-remodeling complexes are among proteins that control the physical state and functional activity of chromatin. The experiment described shortly was designed to study the role of a chromatin remodeling complex designated RSC (Remodeling the Structure of Chromatin) in the regulation of nucleosome dynamics. Figure 1 shows the results of an in vitro experiment....

thank you!!
Question 1 0.5 pts It has been shown that inhibition of a key chromatin remodeling complex known as NURD. by deleting one of its subunits, can result in a significant increase in the efficiency of reprogramming of somatic cells into pluripotent stem cells. The reprogramming is normally done by the induced expression of a battery of transcription factors in the somatic cells, but is typically not very efficient. Such an observation suggests that the NURD complex is normally...

EXAMPLE:
ANSWER 12 :-
From the above mentioned data, the significance of ATP
molecule in the event progression is seen although taking into
consideration that the process is carried out in an in-vitro
manner, the possibility of transcription occuring decreases taking
into consideration the errors associated with the changes in
certain conditions associated with the experimental setup and hence
it becomes difficult to identify if there is actual phosphorylation
occuring of the nucleosomal histone proteins. This in other terms
cannot...
