Question
Chapter 5, Problem 17P
Interpretation Introduction
Interpretation:
The reason corresponding to the fact that the genomic analysis of dogs might be particularly useful for investigating the genes that are responsible for body size and other physical characteristic is to be stated.
Concept introduction:
The basic unit of heredity which is made up of DNA segments is known as gene. The process in which the genomic features like DNA sequence are indentified, measured and compared with others genomic features is known as genomic analysis.

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 Y
