Micro Exam II Virology

Being a microbiology student, you get the chance to understand microbes that commonly have a bad reputation but are beneficial to our lives. One of the topics we have covered so far is virology which helps us understand different viruses and also guides us on understanding diseases and how to cure them. Take the quiz below on the topic in preparation for your Micro exam II.
