which if the following best describes the mechanism by which chromatin remodeling complexes loosen the dna wrapped around the core histones
A) they chemical lie modify the DNa changing the affinity between the histones octaves and the DNA
B) they use energy derived from ATP hydrolysis to change the relative position of the Dan and the core histone octamer
C) they remove histone H1 from the linker DNA adjacent to the core histone octamer

Identify the most accurate term related to chromatin remodeling. DNA is associated with proteins to form. A is compsed of DNA wrapped around an octamer of histone proteins. An activator can increase transcription by attracting a to the region. Addition of (-COCH_3) groups to histone amino terminal tails results in a/an in gene expression. Removal of acetyl groups from histones results in a/an in gene expression.

8. You are studying a newly identified chromatin-remodeling complex, which you call NICRC. You decide to run an in vitro experiment to characterize the activity of the purified complex. Your molecular toolbox includes: (1) a 400-base-pair DNA molecule that has a single recognition site for the restriction endonuclease EcoRI, an enzyme that cleaves internal sites on double-stranded DNA (dsDNA); (2) purified EcoRI enzyme; (3) purified DNase I, a DNA endonuclease that will cleave dsDNA at nonspecific sites if they are...

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...

1. the genes that seem to be the most necessary to maintain, since they are present in the smallest cellular organisms are a. cytoskeletal protein genes b, translation protein genes c. replication protein genes d. transcription protein genes e. DNA repair protein genes 2. Why do cellular organisms generally look very similar when early embryos but different from each other when mature? a. their DNAs have different chemistry b. their RNAs are different lengths c. what genes get turned on...
