Chapter 15.2, Problem 3CC
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.

- 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.

If you find any enhancer, in what genetic region, number of base pairs upstream from MRPA, are they located? Explain.arrow_forwardWHAT 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_forward

Explain your reasoning.arrow_forwardAlignment of protein sequences from the HOX gene family identifies a highly conserved domain in the C-terminal part of the protein that is a domain (one acronym and one word). Although Hox genes have important roles during embryogenesis and tissue differentiation, the different HOX proteins bind to very similar DNA (one word) that are rich in the bases and (one word each). To ensure high affinity binding to (one acronym) and specific regulation of target (one word), the HOX proteins form complexes with (two words).arrow_forward
