Summary Introduction
To interpret:
The results that an individual must expect to obtain when he compares the
Introduction:
The distal control elements are located upstream or downstream within a gene or introns. Control elements (non-coding DNA) serves as binding sites for the transcription factors. It plays a major role to regulate transcription.
Distal control elements or enhancer are located far away from a gene. It presents upstream genes into a DNA and it also contains some regulatory elements.

- D,E,Farrow_forwardshort answer please! thank you!arrow_forwardStrength 22. You are analyzing a new human neuronal enhancer. You cloned the enhancer in front of a minimal promoter, transfected a neuronal cell line, and quantified GFP expression. You then performed the deletion analysis shown on the right. Which letter designates the minimal region where enhancer activity is located? min. Novel enhancer prom. GFP of expression +++ +/- +++ +/- +++ a. a b. b C.

- protein. You create a mouse line with Cas9 under control of a brain-specific enhancer, while the short guide RNA complementary to the first exon of Gene Y is expressed in all tissues. You subsequently sequence Gene Y in both brain and liver tissue. What would expect in each tissue? You can assume that the CRISPRICas9 system will impact both copies of Gene Y in cells, and that the first exon of Gene Y is necessary for Gene Ys function. a. Liver: Functional Gene Y; Brain: Functional Gene Y b. Liver: Nonfunctional Gene Y; Brain: Funtional Gene Y c. Liver: Functional Gene Y; Brain: Nonfunctional Gene Y d. Liver: Nonfunctional Gene Y; Brain: Nonfunctional Gene Yarrow_forwardPls help ASAParrow_forwarda. How many enhancers were you able to identify with these set of experiments? Explain. b. If you find any enhancer, in what genetic region, number of base pairs upstream from MRPA, are they located? Explain.arrow_forward
- WHAT IF? Since the results support a role for mouse FOXP2 invocalization, you might wonder whether the human FOXP2 protein is akey regulator of speech. If you were given the amino acid sequences ofwild-type and mutant human FOXP2 proteins and the wild-type chimpanzee FOXP2 protein, how would you investigate this question? What furtherclues could you obtain by comparing these sequences to that of the mouseFOXP2 protein?arrow_forwardplease help. do 1st problemarrow_forward. Let’s say that you have incredible skill and can isolate the white and red patches of tissue from the Drosophila eyes shown in Figure 12-24 in order to isolate mRNA from each tissue preparation. Using your knowledge of DNA techniques from Chapter 10, design an experiment that would allow you to determine whether RNA is transcribed from the white gene in the red tissue or the whitetissue or both. If you need it, you have access to radioactive white-gene DNAarrow_forward

Explain your reasoning.arrow_forward1. - Which factor(s)/protein(s) would you expect to occur at positions C and G ? (name them) 2. - Would you expect e1, e2, or e3 to be an enhancer for gene t? (explain briefly) 3. - Which genes would you expect to be most likely regulated by enhancer e1? (explain briefly) 4. - In this example genes t - x are expressed but genes y and z are not transcribed. At which position would you expect to see a sharp transition between the chromatin marks H3K27me3 and H3K36me3? (name the position, A - I).arrow_forward
