This glossary features 15 essential biotechnology terms gathered from my career. It serves as a quick reference to help professionals, students, and enthusiasts understand and communicate complex concepts in biotechnology with more clarity.
bioinformatics
noun
An interdisciplinary field that combines biology, computer science, and statistics to analyze and interpret biological data, such as genomic sequences and protein structures.
Example: The research team leveraged bioinformatique to decode large genomic datasets and identify potential therapeutic targets.
fr: bioinformatique
bioprocessing
verb
The use of biological materials, such as cells or enzymes, to manufacture products like pharmaceuticals, chemicals, or biofuels. It encompasses both the upstream (culturing) and downstream (purification) processes.
Example: The company streamlined its bioprocessing methods to boost the efficiency of antibiotic production.
fr: biotransformation
bioreactor
noun
A vessel or system designed to support biologically active environments. Bioreactors are used to scale up cell cultures or microbial fermentation for industrial production.
Example: The research team optimized the bioreactor's conditions to efficiently produce large batches of therapeutic proteins.
fr: bioréacteur
cell culture
noun
is the process by which cells are grown under controlled conditions, generally outside of their natural environment.
Example: Our lab maintained a cell culture of human fibroblasts to evaluate the effects of the new drug candidate.
fr: Culture cellulaire
crispr-cas9
noun
A revolutionary gene-editing tool that uses a guide RNA and the Cas9 enzyme to target and modify DNA sequences with high precision. It has transformed genetic research and therapeutic development.
Example: The researchers applied CRISPR-Cas9 to edit the faulty gene in the cell line, paving the way for potential gene therapies.
fr: crispr-cas9
downstream processing
verb
The steps involved in purifying and isolating a desired product after fermentation or cell culture. This process is crucial for ensuring the quality and safety of biotechnological products.
Example: After fermentation, the company implemented rigorous downstream processing to purify the therapeutic protein before it reached the market.
fr: traitement en aval
fermentation
noun
A metabolic process in which microorganisms convert sugars into acids, gases, or alcohol, often used to produce pharmaceuticals, food additives, and biofuels.
Example: The team optimized the fermentation process to maximize the yield of the biofuel produced from sugarcane.
fr: fermentation
gene expression
verb
The process by which information from a gene is used to synthesize functional gene products, such as proteins. Understanding gene expression is key to deciphering cellular function and regulation.
Example: The researchers measured gene expression levels to determine how the cells responded to the experimental drug.
fr: expression génétique
genomics
noun
The study of an organism's complete set of DNA, including all of its genes and non-coding sequences, to understand genetic variation, function, and evolution.
Example: The researchers employed genomics to identify genetic markers that could predict the likelihood of developing certain diseases.
fr: génomique
metabolomics
noun
The comprehensive analysis of metabolites—small molecules produced during cellular metabolism. This field provides insights into cellular processes and disease states.
Example: Using metabolomics, the team was able to detect subtle shifts in metabolite levels that indicated early stages of metabolic disorders.
fr: métabolomique
monoclonal antibodies
noun
Laboratory-produced molecules engineered to bind to specific antigens, widely used in diagnostics, targeted therapies, and research.
Example: The new cancer therapy utilizes monoclonal antibodies that precisely target tumor cells while sparing healthy tissue.
fr: anticorps monoclonaux
polymerase chain reaction (PCR)
verb
A method used to amplify specific segments of DNA rapidly. PCR is essential for diagnostics, cloning, and various research applications.
Example: The technician used PCR to amplify the patient's DNA sample, allowing for detailed genetic analysis.
fr: réaction en chaîne par polymérase (PCR)
proteomics
noun
The large-scale study of proteins, particularly their structures and functions. Proteomics helps reveal how proteins interact within cells and contributes to drug discovery and disease diagnostics.
Example: Our lab used proteomics to analyze the protein composition of cell samples, uncovering critical biomarkers for early disease detection.
fr: protéomique
recombinant DNA technology
verb
Techniques that involve cutting and recombining DNA from different sources to create new genetic combinations. This is a cornerstone of modern biotechnology, enabling the production of proteins, vaccines, and genetically modified organisms.
Example: The scientists employed recombinant DNA technology to insert the human insulin gene into bacterial cells, paving the way for large-scale insulin production.
fr: technologie de l'ADN recombinant
synthetic biology
noun
A field that applies engineering principles to biology to design and construct new biological parts, devices, or systems, often aiming to create organisms with novel functions.
Example: The startup leveraged synthetic biology to engineer bacteria that could efficiently break down plastic waste, turning it into useful byproducts.
