Was LUCA likely an RNA-based or DNA-based organism? Why?

What was the purpose for doing the colony PCR?

You have found a gene of interest in an animal in the rain forest which produces a unique protein that will blocks reproduction of the pathogen that now plagues the world. You wish to mass produce this protein using bacteria. Answer the following questions regarding the scenario above.  Describe how you would remove the gene of interest out of the isolated animal cell.  What type of vector, (delivery system), would be best used to get the gene into the bacteria? How would you insert the gene of interest into the vector? How would get the vector into the bacteria? Why would the bacteria express this gene even if it normally does not have use for this protein?
