1.Discuss how PCR may be used for the detection of disease-causing pathogens in a population during the COVID Pandemic. For example: it may be used to check if a patient has a COVID virus infection. 2. Discuss how the cloning and expression of certain genes allows for massive production of the desired product. For Example: the cloning and expression of insulin in bacteria allows for the mass production of this necessary protein for use by diabetic patients.

1. Scientists were able to develop transgenic bacteria that can be used for mercury remediation. This process involved combining genes for mercury resistance (so that the bacteria itself has protection) and mercury accumulation (thereby allowing the bacteria to sequester Hg for retrieval later on). They probably used the following techniques in creating the transgenic bacteria EXCEPT a. plasmids b. DNA ligase c. DNA polymerase d. restriction enzymes 2. Consider these two parents (Mom and Dad) and their son, Calvin. (see pic attached). Which two members of this family would show the greatest difference in their DNA profile?

OF intorcat A Intorest gone in a gene "gun," a bacterial material into the genetic material inserts itself into the chromosomes of the host plant. Engineers must also insert a "promoter" gene from a virus as part of the package to make the inserted gene express itself. . This process alone, involving a gene gun or a similar technique, and a promoter, is profoundly different from conventional breeding, even if the primary goal is only to insert genetic material from the same species (Hansen, 2000). host plant cells.
