Acid
An acid is a molecule or ion capable of donating a hydron (proton or hydrogen ion H+), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid).

Activator (genetics)
A transcriptional activator is a protein (transcription factor) that increases gene transcription of a gene or set of genes.
New!!: Regulon and Activator (genetics) · See more »
Ada regulon
In DNA repair, the Ada Regulon is a set of genes whose expression is essential to adaptive response (also known as "Ada response", hence the name), which is triggered in prokaryotic cells by exposure to sub-lethal doses of alkylating agents.
New!!: Regulon and Ada regulon · See more »
Adaptive response
The adaptive response is a form of direct DNA repair in E. coli that protects DNA from damage by external agents or by errors during replication.
New!!: Regulon and Adaptive response · See more »
Chromosome
A chromosome (from Ancient Greek: χρωμόσωμα, chromosoma, chroma means colour, soma means body) is a DNA molecule with part or all of the genetic material (genome) of an organism.
New!!: Regulon and Chromosome · See more »
DNA repair
DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome.
New!!: Regulon and DNA repair · See more »
DNA-binding protein
DNA-binding proteins are proteins that have DNA-binding domains and thus have a specific or general affinity for single- or double-stranded DNA.
New!!: Regulon and DNA-binding protein · See more »
Escherichia coli
Escherichia coli (also known as E. coli) is a Gram-negative, facultatively anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms).
New!!: Regulon and Escherichia coli · See more »
Eukaryote
Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike Prokaryotes (Bacteria and other Archaea).
New!!: Regulon and Eukaryote · See more »
Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations.
New!!: Regulon and Evolution · See more »
Gene
In biology, a gene is a sequence of DNA or RNA that codes for a molecule that has a function.
New!!: Regulon and Gene · See more »
Gene expression
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product.
New!!: Regulon and Gene expression · See more »
Gene regulatory network
A gene (or genetic) regulatory network (GRN) is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression levels of mRNA and proteins.
New!!: Regulon and Gene regulatory network · See more »
Genome
In the fields of molecular biology and genetics, a genome is the genetic material of an organism.
New!!: Regulon and Genome · See more »
Heat shock
In biochemistry, heat shock is the effect of subjecting a cell to a temperature that is greater than the optimal temperature range of function of the cell.
New!!: Regulon and Heat shock · See more »
Homeostasis
Homeostasis is the tendency of organisms to auto-regulate and maintain their internal environment in a stable state.
New!!: Regulon and Homeostasis · See more »
Homology (biology)
In biology, homology is the existence of shared ancestry between a pair of structures, or genes, in different taxa.
New!!: Regulon and Homology (biology) · See more »
Molecular genetics
Molecular genetics is the field of biology that studies the structure and function of genes at a molecular level and thus employs methods of both molecular biology and genetics.
New!!: Regulon and Molecular genetics · See more »
Open reading frame
In molecular genetics, an open reading frame (ORF) is the part of a reading frame that has the ability to be translated.
New!!: Regulon and Open reading frame · See more »
Operon
In genetics, an operon is a functioning unit of DNA containing a cluster of genes under the control of a single promoter.
New!!: Regulon and Operon · See more »
Osmosis
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
New!!: Regulon and Osmosis · See more »
Pathogen
In biology, a pathogen (πάθος pathos "suffering, passion" and -γενής -genēs "producer of") or a '''germ''' in the oldest and broadest sense is anything that can produce disease; the term came into use in the 1880s.

Pathogenicity island
Pathogenicity islands (PAIs), as termed in 1990, are a distinct class of genomic islands acquired by microorganisms through horizontal gene transfer.

Regulation of gene expression
Regulation of gene expression includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA), and is informally termed gene regulation.
