3 segments make up the head with its antennae and mouth parts. 3 segments make up the thorax. Each thoracic segment has a pair of legs (insects are the six-legged creatures).

Segmentation is a result of global optimization of a new objective function that finds the most homologous consequent partition of a given set of aligned sequences. It was developed as a very efficient and simple dynamic programming procedure.

SEGMENTATION The identification of objects above background noise using image- processing methods. Can be achieved by detecting either object boundaries (contour-orientated segmentation) or whole objects (region-based segmentation).

segmentation -- In many animals, the body is divided into repeated subunits called segments, such as those in centipedes, insects, and annelids. Segmentation is the state of having or developing a body plan in this way.

They are all bilaterally symmetrical with some degree of segmentation and they have an internal skeleton. Their unique characteristics include (1) a dorsal hollow nerve cord (most other animals have a ventral nerve cord) above the notochord.

Using specialized DNA technology to produce multiple, exact copies of a single gene or other segment of DNA to obtain enough material for further study. This process, used by researchers in the Human Genome Project, is referred to as cloning DNA.
| |
A ' contig' may refer to a map showing placement of a set of clones that completely, contiguously cover some segment of DNA in which you are interested. Also called the 'minimal tiling path'.
| |
This word can also refer to multiple genes or segments, or even an entire chromosome, where an individual is supposed to have two copies of this gene or chromosome, and they only have a single copy.
| |
Any segment of DNA that can be identified, or whose chromosomal location is known, so that it can be used as a reference point to map or locate other genes.
| |
antenna (plural: antennae). The paired segmented sensory organs, borne one on each side of the head, commonly termed horns or feelers. anthers. The pollen-producing organs of flowers.
| |
Hsp70 chaperones recognize and shield short, hydrophobic peptide segments in the context of non-native polypeptides and probably promote folding by decreasing the concentration of aggregationprone intermediates.
