The meaning of chemical selection. Introduction: Most of the scientists favor RNA to be the very first macromolecule to be found in the protobionts. Comparative studies have shown DNA and proteins to be less versatile in comparison to RNA. During the origin of life on Earth, it is believed to be RNA dominant world. RNA world is believed to exist during the beginning of life on earth. It is a hypothetical period in early earth where both, the information required for maintaining life and the catalytic activities inside a cell were present in RNA itself.

You intend to insert patched dominant negative DNA into the left half of the neural tube of a chick. 1) Which side of the neural tube would you put the positive electrode to ensure that the DNA ends up on the left side? 2) What would be the internal (within the embryo) control for this experiment? 3) How can you be sure that the electroporation method itself is not impacting the embryo? 4) What would you do to ensure that the electroporation is working? How can you tell?

Describe a method to document the diffusion path and gradient of Sonic Hedgehog through the chicken embryo. If modifying the protein, what is one thing you have to consider in regards to maintaining the protein’s function?
