T 1 represents the genetic and epigenetic laws, the aspects of functional biology, or development, that transform a genotype into phenotype. This is the " genotype–phenotype map ". T 2 is the transformation due to natural selection, T 3 are epigenetic relations that predict genotypes based on the selected phenotypes and finally T 4 the rules ...
Project identification is a process in the initiating phase of project life cycle for identifying a need, problem, or opportunity. Once identified, ...
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode ...
In biology, determination is the process of matching a specimen or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists.
Identifying moths. Identification in biology is the process of assigning a pre-existing taxon name to an individual organism.Identification of organisms to individual scientific names (or codes) may be based on individualistic natural body features, [1] experimentally created individual markers (e.g., color dot patterns), or natural individualistic molecular markers (similar to those used in ...
Systematic biology (hereafter called simply systematics) is the field that (a) provides scientific names for organisms, (b) describes them, (c) preserves collections of them, (d) provides classifications for the organisms, keys for their identification, and data on their distributions, (e) investigates their evolutionary histories, and (f ...
The shells of individuals within the bivalve mollusk species Donax variabilis show diverse coloration and patterning in their phenotypes. Here the relation between genotype and phenotype is illustrated, using a Punnett square, for the character of petal color in pea plants.
