Summary Introduction

To write:

The common features which are shared by most of the cell signaling systems.

Introduction:

Cell signaling is a part of any messaging phenomenon which directs the basic actions of cells and manages all the cellular activities.

Expert Solution & Answer

Explanation of Solution

The common features are shared by most of the cell signaling systems. Extracellular signals are produced by other signaling cells. The receptor proteins are located on the target cells. Extracellular signaling molecules bind to the cell-surface receptors and generate a conformational modification in the receptor. This change, in turn, results in the intracellular signal transduction processes. It finally modifies the function, cellular metabolism, or gene expression. These intracellular signal transduction pathways are evolutionarily extremely conserved.

Conclusion

Thus, the common feature of cell signaling systems is extracellular signaling molecules bind to the cell-surface receptors and generates a conformational modification in the receptor and produce a signaling cascade.

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.
