Microbial Genetics: Understanding Microorganisms' Genetic Mechanisms

Microbial chromosomes are often singular and located in the cytoplasm.

Microbial genetics is a field of study that focuses on the genetics of microorganisms, including bacteria, archaea, viruses, and some fungi.

The characteristic structure of microbial chromosomes in many bacteria and archaea is a single, circular DNA molecule.
