Wrong Again. For each of the following false statements, change the statement to make it true.
(a) Archaea are ancient bacteria that are the ancestors of modern bacteria.
(b) Bacteria differ from eukaryotes in having no nucleus, mitochondria, chloroplasts, or ribosomes.
(c) Instead of a cell wall, eukaryotic cells have an extracellular matrix for structural support.
(d) All the ribosomes found in a typical human muscle cell are identical.
(e) DNA is found only in the nucleus of a cell.
(f) Because bacterial cells have no organelles, they cannot carry out either ATP synthesis or photosynthesis.
(g) Even the simplest types of infectious agents must have DNA, RNA, and protein.

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?
