Chapter 21, Problem 4A
Summary Introduction
To write:
The factors made the eradication of smallpox and other diseases which meet these criteria.
Given:
“Smallpox”, “Eradication factors” and “Other diseases”.
Introduction:
Smallpox is an infectious disease caused by an orthopoxvirus or smallpox variola virus. The disease causing virus contains two variants such as Variola major and Variola minor. Variola major has more mortality percentage of 20% compared to the Variola minor variant with 1%.
The artificial vaccine was first developed for smallpox disease and it is the first disease eradicated from the human population.

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage?
Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure?
Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid.

- You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?arrow_forwardYou decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.arrow_forwardYou implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.arrow_forward
