One billion (109) pairs of nucleotide bases in DNA.
Industry:Natural environment
Rock composed primarily of petrified corals or the skeletons of other calcareous animals.
Industry:Natural environment
The connective tissue layer between the epidermis and gastrodermis of cnidarians and ctenophores (comb jellies).
Industry:Natural environment
The number of crossover events observed between two linked loci expressed as a proportion of the total number of meioses sampled.
Industry:Natural environment
The state in which the action of multiple forces produces a steady balance, resulting in no change over time.
Industry:Natural environment
A "fishing rod-like" appendage on the head of some fishes, usually a modified dorsal fin spine.
Industry:Natural environment
A large, isolated rock section that has been displaced from the reef platform, reef margin, reef front zones or the non-calcium carbonate bedrock, usually resulting from storm waves.
Industry:Natural environment
A pattern of small, random deviations between sides in the size of a given trait -the random component of bilateral asymmetry, i.e., subtle random deviations from perfect bilateral symmetry. It arises when genetic or environmental stressors disrupt developmental processes that normally promote symmetrical growth. Fluctuating asymmetry is of particular interest because of its potential as a biomonitor of environmental quality. It is a relatively new tool for assessing the impact of environmental and genetic stresses on populations. One of the main advantages of FA is its increased sensitivity relative to other bioindicators. If effective, this tool could allow biologists to monitor populations and make recommendations before a severe problem arises, often without the high cost of other solutions.
Industry:Natural environment
A small part of the active part of a gene, made from cdna which can be used to fish the rest of the gene out of the chromosome by matching base pairs with part of the gene. The EST can be radioactively labeled in order to locate it in a larger segment of DNA.
