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...
