The Main Themes of Microbiology
Microbiology’s main themes study microscopic organisms, their structure, functioning, evolution and interaction. Microbes are the main subject; thus, bacteria, viruses, protozoa, and algae influence nature and the planet is explored. Indeed, these organisms are the major part of the Earth’s biosphere, and microbiology allows humanity to indicate crucial changes, understand the reasons for current environmental issues, and forecast how life will be in the future (Anderson et al., 2021). The major features of this field of study are an exploration of viruses’ nature and evolution, characterization of prokaryotes and eukaryotes, the influence of bacteria and archaea on human health, naming and cultivating microorganisms, and microbial observation (Anderson et al., 2021). Moreover, the science contributes to epidemiology and provides vital insights into how modern technology may address problems such as climate change.
Evolution, Classification, and Naming of Microorganisms
Evolution of microorganisms displays how genetic modifications occurred throughout time to help bacteria adapt to changing conditions. Microbial growth resulted in vast genomic plasticity, and viruses helped drive the development by forcing the organisms to address infections. Microorganisms are classified by their biochemical testing results, DNA composition, morphological characteristics, and polymerase chain reaction (Anderson et al., 2021). For instance, microbes may be grouped as prokaryotic or eukaryotic based on their structure and reproduction mode. The naming of microorganisms is based on binomial nomenclature, as the two words are necessary to identify the species and the genus, which is always capitalized (Anderson et al., 2021). The Latin language is used for names and may include descriptive terms, geographic origins, scientists’ names and organizations.
Overview of the Chemistry of Biology
The chemistry of biology explores how atoms, bonds, molecules, and organic compounds, common to all cells, interact with their environment. Indeed, chemical reactions in all living organisms are based on molecular interactions, and the discipline identifies their main characteristics and operations. Chemistry of organic compounds studies how hydrogen atoms evolve into new forms (Anderson et al., 2021). For instance, molecules combine as the nucleus of each atom connects, resulting in building tissues and organs.
