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. The reaction mixtures contained a 32-labelled 154 basepair...

1.) Transcription a.) Every non-general transcription factor (e.g. CREB1) needs at least two functional domains to initiate transcription. Name and describe the function of these two domains. (15 words per domain)(10 points) b.) How is chromatin around active promoters different from a transcriptionally inactive areas of the genome? (30 words) (10 points) c.) TFIIH is a general transcription factor with Helicase and Kinase activity. Describe how these two activities assist RNA Pol II with transcription initiation? (30 words) (10 points)

Why are the Hubble Constant, the Cosmological Constant, and the density parameter so important to cosmology and to you? Consider expansion rate and age. What would be different about our universe if the Hubble Constant were doubled from its current value? How do these constants factor into the geometry of spacetime? How have these constants changed throughout the lifetime of the universe? Are they still changing? Cite some evidence to support your claims. Please type answer, last persons handwriting was...
