The study of how organisms are classified based on shared characteristics.

Arranging organisms into groups based on their shared features, it's like sorting laundry by color.

The process of assigning specific names to organisms. It's like giving everyone in your family a unique nickname.

Living beings that are composed of cells, including those with a nucleus (Eukarya) and those without (Bacteria and Archaea).

Living beings that lack cells, such as viruses, viroids, and prions. They require a host to reproduce.

A hierarchical system used to classify living organisms, spanning from broad categories like 'Domain' down to specific species. It's like a family tree for all life.

The broadest category in the taxonomic hierarchy, encompassing all living organisms. Think of it as the grandparent category.

A group of organisms with a shared set of characteristics. It's like a big family with similar traits.

A group of organisms within a Kingdom, often with distinctive physical features. It's like a branch of the family tree.

A group of organisms within a Phylum, with shared anatomical features. It's like a specific group within a family, like cousins.

A system for classifying the risk posed by microorganisms to humans and the environment, with four categories ranging from minimal to severe.

A group of microorganisms that pose a potential threat to human health, requiring specific laboratory facilities and safety protocols.

A set of precautions and levels of containment used in laboratories to handle dangerous microorganisms safely.

A laboratory environment designed to prevent the accidental release of dangerous microorganisms, with specific safety regulations and equipment.

A type of safety cabinet used in laboratories to protect workers and the environment from potentially infectious agents.

A specific change in a single DNA base, potentially altering the protein encoded by a gene.

The study of evolutionary relationships between organisms, often visualized as branching diagrams.

Aligned sequences of DNA or protein from different organisms, used to compare their similarities and differences.

A measure of how similar two genetic sequences are, expressed as a percentage.

A diagram that represents the evolutionary relatedness between organisms, showing the branching pattern of their ancestry.

A phylogenetic tree where a common ancestor is identified, providing a timeline of evolutionary history.

A phylogenetic tree that doesn't show a common ancestor, but only the relationship between organisms.

The process of acquiring new genes from other organisms, often through transfer of DNA.

A group of living organisms capable of interbreeding, even if geographically isolated.

A collection of strains sharing stable properties, but significantly different from other groups.

A genetic variant or subtype of a bacterial species, varying slightly from others in the same species.

Observable characteristics or traits of an organism, including morphology, development, biochemistry or physiological properties.

Distinct variations in cell surface antigens within a species.

The part of the genetic makeup of a cell that determines one of its characteristics.

The complete DNA sequence of an organism at a single time.

The passage of genetic information from parent to offspring.

The acquisition of genetic information by transfer from an organism that is not its parent.

Genomes of bacterial species are at least 95% identical. However, horizontal gene transfer can complicate this definition.

A laboratory designed to handle agents that pose a serious risk to human health, requiring stringent safety protocols and specialized equipment.

A type of classification based on the observable characteristics of a microorganism, like its shape or its ability to grow in specific environments.

Microbial agents that cause severe human disease often resulting in death, with a high risk of spreading within a population and lacking effective treatment options.

A system for classifying microorganisms based on their potential risk to human health, animals, and the environment. Each level indicates increasing containment measures needed for safety.

A type of classification based on the genetic makeup of a microorganism, often using techniques like DNA sequencing.
