Concept explainers
(a)
Interpretation:
The effect of cholesterol feeding on the amount of HMG-CoA reductase mRNA should be determined.
Concept introduction:
Cholesterol is an organic lipid molecule. It is a steroid which is synthesized in all animal cells and is an important component of cell membrane. Cholesterol also functions to serve as a precursor for steroid hormones, vitamin D, and bile acid. In vertebrates, cholesterol is produced by the hepatic cells.
(b)
Interpretation:
The purpose isolating actin mRNA must be determined.

(c)
Interpretation:
The effect of cholesterol diet on the HMG CoA reductase protein should be determined.

Cholesterol also functions to serve as a precursor for steroid hormones, vitamin D, and bile acid. In vertebrates, cholesterol is produced by the hepatic cells.
(d)
Interpretation:
The reason for surprising results in graph B.

- Need helparrow_forwardprotein. 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_forwardPlease ASAP. Thank youarrow_forward

What happens to the protein amount, protein purity, and/or specific activity of a purification fraction if one of the three is changed? (i.e. understand the relationship between the three.)arrow_forwardHi, help please. Which of the following is TRUE regarding RNA editing? a .The coding sequence is altered in the chromosome b. More than one answer choice is correct c. The mRNA is altered by Guide RNAs d. Translation first takes place, following by altering of the coding sequencearrow_forward
