Re c e n t a dva n c e s in m o l e c u l a r b io l og y t ech n i q u e s p er m i t scientists to identify genetic contributions to alcoholism. Two main types of technology are commonly used to identify genes that cause or predispose a person to a disease: positional cloning techniques and candidate gene techniques. Positional cloning techniques allow disease genes to be identified based solel y o n t hei r loc a t ion w i th in t h e genom e wi t h o ut p rior knowledge of the gene’s function. Techniques for confirming t h e r o l e o f c a n d i d a t e g e n e s r e l y o n s u f f i c i e n t p r i o r understanding of the disease process to implicate possible disease­related genes. Scientists use cloning techniques or the application of certain enzymes to reproduce a candidate gene in sufficient quantity for study. As the human genome project progresses and the gene map becomes increasingly complete, more and more disease genes will be identified through a combination of positional cloning and the candidate gene ap p r oac h.

Using two retrotransposon-based marker systems (SRAP and REMAP) for genetic diversity analysis of Moroccan Argan tree

The Argania is an endemic genetic resource in Morocco holding an important ecological and socio-economical benefit. However, overgrazing and overharvesting lead to a serious downturn in the number of trees. To characterize genetic diversity within and among 24 populations, represented by 240 argan trees, four combinations of SRAP primers and eight combinations of REMAP primers were used. A tota...

Genetic diversity analysis of aquaculture strains of Acipenser stellatus (Pallas, 1771) using DNA markers

Acipenser stellatus (stellate sturgeon) represents a sturgeon species of great importance for the scientific community and fishermen that has been intensively captured for decades. Besides of overfishing and poaching, their reproduction sites have been destroyed and their natural habitats were affected by pollution. In consequence, wild populations of stellate sturgeon have decreased dramatical...

Genetic Variation Among Salvia Species Based on Sequence-Related Amplified Polymorphism (SRAP) Marker

In this study, SRAP molecular maker approach was performed to investigate genetic diversity in the Salvia genus. A total of 205 DNA bands were produced from PCR amplification of 11 Salvia species and populations using 25 selective primer combinations, of which 204 polymorphic genetic loci accounted. The total number of amplified fragments ranged from 3 to 15. The genetic similarities of 11 coll...

Genetic Diversity of Bread Wheat (Triticum aestivum L.) Genotypes Using RAPD and ISSR Molecular Markers

The importance of grain cultivation especially wheat is obvious in terms of providing human and animal food and its impact on the economy of human societies. The reduction of genetic diversity in cultivars prevents increasing yields in line with rising demand and consumption. Therefore, it is necessary to improve the compatibility of them and increase their genetic extent. In the current, the g...
