A SNP (pronounced "snip") is a small genetic change, or variation, that can occur within an organism's DNA sequence. The genetic code is specified by the four nucleotides: adenine, cytosine, thymine, and guanine. SNP variation occurs when a single nucleotide, such as adenine, replaces one of the other three nucleotides. Snps found within a coding sequence are of particular interest to researchers because they are more likely to alter the biological function of a protein. Because of the recent advances in technology, coupled with the unique ability of these genetic variations to facilitate gene identification, there has been a heightened activities of SNP discovery and detection.
Industry:Natural environment
A type of cleavage characteristic of deuterostomes. When changing from a four-cell stage to an eight-cell stage embryo, the cells divide such that each cell in the top four cell plane is directly over one other cell in the bottom plane.
Industry:Natural environment
An enzyme used to join DNA (DNA ligase) or RNA (RNA ligase) segments together.
Industry:Natural environment
Any species of brightly colored reef-dwelling bony fishes in the family Acanthuridae which have laterally compressed bodies and possess one or more sharp erectile spines near the base of the tail; also called "tangs" and "doctorfish" .
Industry:Natural environment
Fan-shaped, paired posterior abdominal appendage in certain crustaceans, e.g., lobsters or shrimp, that are used for swimming.
Industry:Natural environment
In statistics, the value of a test statistic at or beyond which the null hypothesis is rejected.

On ascending from a dive, a safety stop is a specified time spent by a scuba diver at a specific depth, for nitrogen off-gassing. While not mandatory during a no-decompression dive, it is a sound safety practice. A safety stop may be 3-5 minutes at 10-15 ft below the surface.
Industry:Natural environment
The concept that one gene in DNA codes for a sequence of amino acids in a specific polypeptide.
Industry:Natural environment
A diffuse, two-dimensional plexus of interconnected bipolar or multipolar neurons with no central control organ; found in cnidarians.
