Chromatin structure creates a challenge for eukaryotic transcription because:
there are many ionic bonds between histones and DNA ina nucleosome, making it energetically expensive to remove histones
QUESTION 4 Chromatin structure creates a challenge for eukaryotic transcription because (choose all that apply;: □Eukaryotic...
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.
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...
