Chapter 15.1, Problem 3MC
Summary Introduction
To determine:
Why the RNA is likely to have been pivotal in life’s beginning.
Concept introduction:
Some investigators suggest that RNA were the first genetic material. They have used the term “RNA world” to describe this phenomenon. The RNA has several characteristics that make it suitable for carrying genetic information and transmitting it from one generation to another.

- Using quail and chick embryos, quail-specific antibody and fluorescent tissue-specific antibodies, design an experiment where you investigate the tissues the cranial neural crest can give rise to. What are four derivatives of the cranial neural crest that you expect to see in the resulting chimeric embryos?arrow_forwardDoes the neural crest have to undergo epithelial to mesenchymal transition prior to migration through the developing embryo? Does the neural crest differentiate into different cell types based on their axial position along the anterior and posterior axis?arrow_forwardUsing quail and chicken embryos, what kind of experiment would you conduct to test if rib forming somites have their axial identity specified before segmentation? How do we know this phenotype is due to axial identity being specified before segmentation and not due to our experimental method?arrow_forward
- 8. Aerobic respiration of a 5 mM solution of tripeptide that is composed of the following three amino acids; alanine, leucine and isoleucine. Alanine breaks down to pyruvate, leucine breaks down to Acetyl-CoA and isoleucine breaks down to succinyl-CoA.

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. Assume no other carbon source is available. fatty acids glycerol 18 carbons 12 carbons 0=arrow_forwardinfluences of environment on the phenotype.arrow_forward

- 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
