- Company Profile:
The proximity of two or more markers (e.g., genes, RFLP markers) on a chromosome; the closer the markers, the lower the probability that they will be separated during DNA repair or replication processes (binary fission in prokaryotes, mitosis or meiosis in eukaryotes), and hence the greater the probability that they will be inherited together..
Industry:Biology
Where alleles occur together more often than can be accounted for by chance. Indicates that the two alleles are physically close on the DNA strand.
See also: Mendelian inheritance.
Industry:Biology
Determination of the original position (locus) of a gene or other marker on a chromosome..
Industry:Biology
Analysis of biological material by detection of the light-absorbing or fluorescing properties of cells or subcellular fractions (i.e., chromosomes) passing in a narrow stream through a laser beam. An absorbance or fluorescence profile of the sample is produced. Automated sorting devices, used to fractionate samples, sort successive droplets of the analyzed stream into different fractions depending on the fluorescence emitted by each droplet..
Industry:Biology
The study of genes, their resulting proteins, and the role played by the proteins the body's biochemical processes..
Industry:Biology
Mature male or female reproductive cell (sperm or ovum) with a haploid set of chromosomes (23 for humans)..
Industry:Biology
The study of genes and gene function in bacteria, archaea, and other microorganisms. Often used in research in the fields of bioremediation, alternative energy, and disease prevention.
See also: model organisms, biotechnology, bioremediation.
Industry:Biology
Chromosome fragments that are not incorporated into the nucleus at cell division..
