Before you submit your exam, hold up your notes page & scratch paper for the camera again. You’ll need to submit pictures of them in the final assignment in this module in order to complete the exam work. Thank you for all your hard work this semester! I have enjoyed working with you, and I hope to see you again in a future course. Have a wonderful summer!

Researchers are studying a group of small mammals. During the period of their study, a period of severe winter cold occurs. The researchers find that larger individuals have higher survival through the storm than smaller individuals. The researchers hypothesize that there may be natural selection causing evolution of body size in this group of mammals. What else would they have to determine in order to tell whether body size could currently be evolving as a result of natural selection?

A group of students want to engineer bacteria to produce a protein coded for by a human gene (humans are eukaryotes; our cells are eukaryotic cells). They find the gene in human DNA and cut it out of the chromosome. They replace the human promoter & terminator with a bacterial promoter & terminator, then they add it to a plasmid. They insert the plasmid into bacterial cells. A) Did they have to add the bacterial promoter and terminator to the gene in order for it to be expressed in the bacteria? B) Based on what the students have done, will the bacterial cells be able to produce the human protein correctly?
