Chapter 11, Problem 39SAE
Summary Introduction
To review:
The effect of increased renin levels on blood pressure and its mode of action needs to be reviewed.
Introduction:
The maintenance of blood pressure is an important homeostatic mechanism. This maintenance is performed by a number of regulatory factors such as neural factors and chemical factors. Renin is one of the chief biochemical factors that regulates blood pressure and helps in the maintenance of homeostasis.

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
