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...

Hello! Can someone help me answer this please?
1. Answer the following questions about chromosomal and extra-chromosomal DNA: A. A previously undiscovered single-cell organism was found living at a great depth on the ocean floor. Its nucleus contained only a single linear chromosome with 7* 106 nucleotide pairs of DNA coalesced with three types of histone-like proteins. A short micrococcal nuclease digestion yielded DNA fractions of 700, 1400, and 2100 bp. Predict what these fractions represent. What conclusions can be...
