General Microbiology

Question 1.

Define the word ubiquitous, and provide examples showing why this is an appropriate term to use when describing microbes.

Question 2.

You are a researcher researching Zika virus, a mosquito-borne pathogen. The number of cases of Zika have skyrocketed over the past few months and the weather service has recorded the data showing that this summer has been the wettest in the past 50 years. Using the scientific method, develop a sound hypothesis explaining the increase in disease cases and a method for testing this hypothesis.

Question 3.

Humans have learned through history how to use the abilities of microbes to their advantage. Considering ways that we use them (not how they naturally have become part of our microflora), describe 3 methods used in the environment, industry, and in our daily lives.

BIOL 110

1 TAKE HOME EXAM FOR THE MOLECULAR GENETICS REVIEW BIOL 110 To understand microbiology, it is essential to have a fairly good understanding of such basic points of molecular genetics (proteins, enzymes, DNA, RNA, transcription, translation, and mutation. The purpose of this take home exam is to enable you – or force you if you prefer – to review these topics that you learned in your prerequisite course, BIOL 110. It will also introduce you to mechanisms of genetic recombination in bacteria. Read the Review of Molecular Genetics for Take Home Exam included in your hard copy of my Lecture Guide. It can be found at the end of Part-1 of my BIOL 230 Lecture E-text following the Unit 3 segment. I would urge you to use the hard copy of this material in conjunction with the illustrations and animations in the online version found on my web page at http://faculty.ccbcmd.edu/courses/bio141/lecguide/takehome/index.html After you read these sections and study the illustrations and animations, answer the enclosed Take Home Exam. OBJECTIVES FOR TAKE HOME EXAM FOR THE MOLECULAR GENETICS (DO NOT ANSWER THESE.) While you don’t have to turn in the Objectives listed below, these are objectives I would expect you to be fairly fluent with before we get very far into this course.
