- Company Profile:
An agent that causes a permanent genetic change in a cell. Does not include changes occurring during normal genetic recombination..
Industry:Biology
A nitrogenous base, one member of the base pair AT (adenine-thymine).
See also: base pair, nucleotide.
Industry:Biology
The capacity of a chemical or physical agent to cause permanent genetic alterations.
See also: somatic cell genetic mutation.
Industry:Biology
The study of how genomes respond to environmental stressors or toxicants. Combines genome-wide mRNA expression profiling with protein expression patterns using bioinformatics to understand the role of gene-environment interactions in disease and dysfunction..
Industry:Biology
A full set of genetic material consisting of paired chromosomes, one from each parental set. Most animal cells except the gametes have a diploid set of chromosomes. The diploid human genome has 46 chromosomes.
See also: haploid.
Industry:Biology
The synthesis of an RNA copy from a sequence of DNA (a gene); the first step in gene expression.
See also: translation.
Industry:Biology
A nitrogen-containing molecule having the chemical properties of a base. DNA contains the nitrogenous bases adenine (A), guanine (G), cytosine (C), and thymine (T).
