Summary Introduction
Sulfolobus is one of the best-studied members of Crenarchaeota. Sulfolobus members are spherical, aerobic, and irregularly lobed. They can thrive in a temperature optimum of about 80 ̊ C and the pH optimum of 2-3. Thus, they are referred to as thermoacidophiles. Under oxic conditions, Sulfolobus species able to grow chemoorganotrophically and also grow chemolithoautotrophically, consuming H2S, H2, and FeS2 as electron donors and consuming oxygen as the terminal electron acceptor (though the use of ferric iron has been reported). Sulfolobus species use HP/HB cycle when growing chemolithoautotrophically and when growing chemoorganotrophically, they use the Entner-Doudoroff pathway (nonphosphorylative version), and tricarboxylic acid cycle (TCA).

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?
You 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.
You 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.

- Which ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
