A chromatin immunoprecipitation (ChIP) experiment for RNA polymerase II (RNAP2) is carried out, specifically to tell the difference between RNAP2 bound to the promoter and RNAP2 that has escaped the promoter but has not yet begun to fully elongate (RNAP2 serine 5 phosphorylated).

Describe two issues that might come up when designing your experiment to obtain the type of data you desire. Also provide a solution to address these two issues.

One way to discover promoters is through an experiment called RNA polymerase protection assay, in which RNA polymerase binds to a gene, is cross-linked to the DNA, and then the DNA is subjected to fragmentation, which breaks apart any DNA that is not protected by cross-linked protein. Explain why this would help to identify promoters in genes.

"RNA polymerase II activity depends on both cis-regulatory elements and trans-acting factor A) What is the main difference between cis-regulatory elements and trans-acting factors? (Hint: which of the two are DNA sequences, and which one are proteins?) B) Name and briefly describe the three cis-regulatory elements we have studied in eukaryotes" University-level genetics course, please keep answer as simple and to the point as possible (preferably in bulleted list)... Thank you!

An experiment was carried out to investigate the effect of species (factor A, with I = 4) and grade (factor B, with J = 3) on breaking strength of wood specimens. One observation was made for each species—grade combination—resulting in SSA = 443.0, SSB = 424.6, and SSE = 125.4. Assume that an additive model is appropriate. (a) Test H0: α1 = α2 = α3 = α4 = 0 (no differences in true average strength due to species) versus Ha:...
