Von Gierke disease is frequently the result of a defect in glucose 6-phosphatase. Suggest another mutation in glycogen metabolism that could cause symptoms like those of von Gierke disease. Explain why the two mutants would likely share symptom profiles.

12. Answer a few questions about sickle cel What protein is mutated in a person with sickle cell anemia? With respect to the protein, What TYPE of mutation causes sickle cell anemia? What specific amino acid(s) have changed in the protein, and how specifically does the DNA code for the mutant gene differ from the "normal" gene? How does this mutation in one protein cause the disease sickle-cell anemia? Which person in the pictures at the beginning of this section...

Explain what classifies a mutation as “temperature‑sensitive” by comparing phenotype(s) with a wildtype allele. How is this type of phenotype explained by protein behaviour? Would the following types of mutations most likely have: severe effects, mild effects, or no effect on protein function? Briefly explain your answers. Note that there may be more than one correct answer, but you need only to give one sensible answer and explain your reasoning. [6 marks] A nonsense mutation occurring in sequences encoding amino...

You are still a neurobiologist studying social cells in the brains of zebrafish. Your colleague points out that an inherited neurological disorder that affects social behavior is linked to a gene that controls ER assembly called ERGIC1. You decide to follow up on this by making a new transgenic animal that will express GFP in social cells, however this time the GFP will be restricted to the ER. This will allow you to monitor the structure of the ER in...

Zebrafish are an important model organism used to study genetics and the development of organ systems. In addition to being a vertebrate, zebrafish develop most of their organ systems in about three days following fertilization and during this time the developing fish is clear, allowing easy visualization of developmental processes. Furthermore, it is easy to maintain and breed these fish, and a single female can lay hundreds of eggs that can then be used in studies. You are analyzing the...

. What does alcian blue stain? 2. What does alzerin red stain? How do you predict LiCl treatment of zebrafish embryos will affect anterior-posterior axis formation? Will the fish have diminished anterior structures and expanded posterior structures or will the fish have expanded anterior structures and diminished posterior structures? 6. In LiCl treated fish, what parts of the skeleton (bone or cartilage) do you predict will be absent? 7. How do you predict cyclopamine treatment of zebrafish embryos will affect...

Imagine an individual with a mutation such that they can not express Vpre-B protein. Answer the following: When is VPre-B normally expressed (specific cell development stage and in what tissue)? To what, specifically, does Vpre-B bind? What are the outcomes of Vpre-B surface expression? In the absence of Vpre-B expression, what is the most likely outcome for the patient? (what is the limitations of their immune system)?
