Comparative analysis of molecular sequence data is essential for reconstructing the evolutionary histories of species and inferring the nature and extent of selective forces shaping the evolution of genes and species. Here, we announce the release of Molecular Evolutionary Genetics Analysis version 5 (MEGA5), which is a user-friendly software for mining online databases, building sequence align...
Recent advances in DNA microarray offer the ability to monitor and measure the expression levels of thousands of genes simultaneously in an organism. These experiments consist of monitoring each gene many times under different conditions or evaluating each gene under a single environment but in different types of tissues. The first one is useful for identification of functionally related genes ...
One of the most important processes of erosion and sediment transport in streams is the river most complex engineering issues.this process special effects on water quality indices, action suburbs floor and destroyed much damage to the river and also into the development plans Lack of continuity sediment sampling and measurement of many existing stations. due to the low number of hydrometric s...
