(archaeon, sing.) In Woese's taxonomy, domain that includes all prokaryotic cells having archaeal rRNA sequences.
chemistry dealing with chemical compounds and processes in living plants and animals.
Branch of chemistry that studies the chemical reactions of living things.Gene therapy
The use of recombinant DNA technology to insert a missing gene or repair a defective gene in human cells.
Branch of microbiology in which microbes are manipulated to manufacture useful products.
Any unicellular microorganism that lacks a nucleus. Classification includes bacteria and archaea.
Technique for staining microbial samples by applying a series of dyes that leave some microbes purple and others pink. Developed by Christian Gram in 1884.
Component of a nucleotide consisting of a nitrogenous base and a five-carbon sugar.
Endoplasmic reticulum (ER)
Netlike arrangement of hollow tubules continuous with the outer membrane of the nuclear envelope and functioning as a transport system.
A microorganism capable of causing disease.

The use of light or electrons to magnify objects.
Healthcare-associated disease (nosocomial disease)
A disease acquired in a health care facility.
Smooth endoplasmic reticulum (SER)
Type of endoplasmic reticulum that lacks ribosomes and plays a role in lipid synthesis and transport.
Characteristic of a solution having a higher concentration of solutes than another.
Type of phase microscope that produces sharply defined images in which fine structures can be seen in living cells.
Active process, occurring in some prokaryotes, by which a substance being actively transported across a cell membrane is chemically changed during transport.
The attraction of an atom for electrons.
An atom or group of atoms that has either a full negative charge or a full positive charge.
