Summary Introduction

To examine:

The fatty acid that may be the best to protect the membranes of an ice-dwelling bacterium.

Introduction:

Lipids are organic compounds containing carbon, hydrogen, and oxygen in ratio 1:2:1 (approximately) and in low amount phosphorus, sulfur or nitrogen. Lipids are included fatty acids, glycerides, steroids, phospholipids, and a glycolipid.

Fatty acids are long chains of hydrocarbons that are capped through a carboxyl functional group. Fatty acids are also termed as triglycerides because three fatty acids are joined to glycerol. Fatty acids differ with each other due to their presence and location of double bonds among carbon atoms. Saturated fatty acids contain only “single bonds” between their carbon atoms, while unsaturated fatty acids contain “double bonds” between carbon atoms.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
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.
