How Can We Use DNA to “See” Inside Microbes?

Abstract

Have you heard of bacteria and viruses? They are a part of a field of science called microbiology, which is the study of small organisms that cannot be seen with the naked eye. These tiny organisms are often called microbes or microorganisms. The scientists who study them are called microbiologists. Microbes are important to study because there are many living in us and around us. Some microbes can make people sick, but the majority do not harm us, and some can even help us. Some microbes can also help the environment and others can be used to treat and prevent diseases. Since we cannot see these small creatures, there are special tools scientists use to study them. In this article, we will discuss how scientists can study microbial DNA to make advances in medicine and environmental science.
