You must use current references (2015 - 2019) unless approved by your instructor. You may include reputable Internet resources in your search. However, all Internet resources, with no “hard” sources, is not acceptable. At least one of the references should be from a peer-reviewed scientific journal. Examples of these would include Science, Nature, Cell, PNAS, Journal of Bacteriology, and others of that nature. An online version of a journal is acceptable. Sites such as Wikipedia are not acceptable sources. For this length of paper, you should have no fewer than 5 resources unless previously approved by your instructor. It is appropriate to use older resources as historical information, but they should be in addition to those mentioned above.
