The environment in which parameters, such as light, temperature, salinity, etc., are fully controlled.
Industry:Natural environment
The principal statement of the molecular basis of gene action. Genetic information is stored in and transmitted as DNA. Genes are expressed by being copied as RNA ( transcription), which is processed into mrna (messenger RNA) via splicing and polyadenylation. The information in mrna is translated into a protein sequence using a genetic code to interpret three-base codons as instructions to add one of twenty amino acids, or to stop translation; or more simply put, DNA carries the genetic information which is transcribed to RNA and subsequently translated to protein. Francis Crick, the co-discoverer of the double helix structure of DNA, coined the term "Central Dogma" in 1958 to characterize the all-important cellular processes whereby DNA is "transcribed" into RNA and RNA is "translated" into protein.
Industry:Natural environment
The union of a large nonmotile egg with a small motile or nonmotile male sperm cell.
Industry:Natural environment
The reformation of double stranded DNA from thermally denatured DNA. The rate of reassociation depends upon the degree of repetition and is slowest for unique sequences.
Industry:Natural environment
A chemical substance that induces a response in an individual of another species that is beneficial to the emitting organism. Many allomones are essentially chemical deterrents. For example, a chemical substance that is produced by a prey species to repel a predator species.
Industry:Natural environment
A form of reproduction where the offspring are nourished in the reproductive tract of the female (other than by a yolk sac) and then expelled from the mother as free-swimming young. Mangrove reproduction by means of propagules is also a form of viviparity in plants.
Industry:Natural environment
A measure of the resistance to change, with time, of the sequence of genes within a DNA molecule or of the nucleotide sequence within a gene.
Industry:Natural environment
A quadrat that is photographed for purposes of later analysis and permanent record for species monitoring or measurement.
Industry:Natural environment
A structure extending into the ocean to influence the current or tide in order to protect harbors, shores, and banks.
