Shotgun sequencing. In genetics, shotgun sequencing is a method used for sequencing random DNA strands. It is named by analogy with the rapidly expanding, quasi-random shot grouping of a shotgun . The chain-termination method of DNA sequencing ("Sanger sequencing") can only be used for short DNA strands of 100 to 1000 base pairs.
V (D)J recombination (variable–diversity–joining rearrangement) is the mechanism of somatic recombination that occurs only in developing lymphocytes during the early stages of T and B cell maturation. It results in the highly diverse repertoire of antibodies/immunoglobulins and T cell receptors (TCRs) found in B cells and T cells, respectively.
Linkage disequilibrium. In population genetics, linkage disequilibrium ( LD) is a measure of non-random association between segments of DNA ( alleles) at different positions on the chromosome ( loci) in a given population based on a comparison between the frequency at which two alleles are detected together at the same loci and the frequencies ...
In geometry, a line segment is a part of a straight line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints. It is a special case of an arc, with zero curvature. The length of a line segment is given by the Euclidean distance between its endpoints. A closed line segment includes both ...
CRISPR gene editing. CRISPR-Cas9. CRISPR gene editing (CRISPR, pronounced / ˈkrɪspər / "crisper", refers to " c lustered r egularly i nterspaced s hort p alindromic r epeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial ...
Proton GEN•2. The Proton GEN•2 (often simplified as Gen-2 or GEN2) is a compact 5-door liftback manufactured by Malaysian automobile manufacturer Proton which launched in 2004. [2] It was initially codenamed Wira Replacement Model (WRM). The GEN•2 uses a platform which was extensively developed in house by Proton and technical partner Lotus.
A second goal of this literature scan is to provide REL staff resources and strategies for sifting through the array of tools available for measuring career readiness in ways that are valid, reliable, fair, and useful in different contexts. To address these two goals, this literature scan includes two sections.
In electrocardiography, the ST segment connects the QRS complex and the T wave and has a duration of 0.005 to 0.150 sec (5 to 150 ms). It starts at the J point (junction between the QRS complex and ST segment) and ends at the beginning of the T wave. However, since it is usually difficult to determine exactly where the ST segment ends and the T ...
