A gene found in different species that evolved from a common ancestral gene by speciation. Normally, orthologs retain the same function in the course of evolution.
Industry:Natural environment
A method of detecting the presence of specific nucleic acid sequences within a cytological preparation. A DNA or RNA probe is labeled, radioactively or chemically, and hybridized to a cytological preparation to detect RNA, or to a denatured cytological preparation to detect complementary DNA. The hybridization is detected by autoradiography (for radioactive probes) or by chromogenic reactions or fluorescence (for chemically-labeled probes).
Industry:Natural environment
A relation between a variable and one or more related variables.
Industry:Natural environment
A substrate formed by the deposition of calcium carbonate by reef building corals and other organisms or existing as bedrock or volcanic rock usually of minimal relief.
Industry:Natural environment
Also called raster or paint images. They are made of individual dots called pixels (picture elements) that are arranged and colored differently to form a pattern. Compared to a vector image, bitmap images are great for photographs because they tend to offer greater subtleties for shading and texture but require more memory and take longer to print. Vector images are best for drawings that need sharper lines, more detail, and easy modification. Vector images require far less printing resources than bitmap images.
Industry:Natural environment
Coarse sediment typically found in areas exposed to currents and wave energy.
Industry:Natural environment
In animal behavior, the temporary waning or disappearance of an innate response when it is elicited many times in succession.
Industry:Natural environment
Instead of solely replacing defective genes, gene-based medicine is the application of nucleic acids (DNA, RNA) containing genetic information as therapeutic reagents in general. Nucleic acids are used to add a therapeutically beneficial function to cells, delete pathological functions from cells, or utilize cells for the production of therapeutic proteins. This can be either a transient or a permanent effect.
Industry:Natural environment
Pertaining to, or situated near, the belly, or underside, of an animal.
