Short interspersed elements (SINEs) make up a significant fraction of total DNA in mammalian genomes, providing a rich substrate for chromosomal rearrangements by SINE-SINE recombinations. Proliferation of mammalian SINEs is mediated primarily by long interspersed element 1 (L1) non-long terminal repeat retrotransposons that preferentially integrate at DNA sequence targets with an average lengt...

Two homochiral building blocks featuring a protected thiol, an alkene and a H-bond recognition unit (phenol or phosphine oxide) have been prepared. Iterative photochemical thiol–ene coupling reactions were used to synthesize oligomers containing 1-4 phosphine oxide and 1-4 phenol recognition sites. Length-complementary H-bond donor and H-bond acceptor oligomers were found to form stable duplexe...

  Mahisefid is the most popular fish in Iran with the highest economic value. The analysis of mitochondrial DNA has been extensively used as a marker for population genetic studies and is a powerful tool in studies of gene flow and evolutionary biology. Two hundred ninety four samples were collected from Sefid Rud River (100), Lamir River (98), Shir Rud River (48) and Tajan River (48) during s...

The prothrombinase complex catalyzes the activation of prothrombin to alpha-thrombin. We have repetitively shown that amino acid region (695)DYDY(698) from the COOH terminus of the heavy chain of factor Va regulates the rate of cleavage of prothrombin at Arg(271) by prothrombinase. We have also recently demonstrated that amino acid region (334)DY(335) is required for the optimal activity of pro...

A mild hemolytic anemia in a 43-yr-old black likely explanation of the instability is the woman was attributed to the presence of an abpresence of an uncovered positive chargs in the normal hemoglobin (Hb Rush) which migrated central cavity where normally glutamic acid in cathodically to Hb A at pH 8.0. Its structural position 101 neutralizes arginine in position abnormality was found to be in ...

Wild relatives of cultivated potato are used in breeding to increase the genetic diversity Solanum tuberosum (AAAA genome) varieties. Mexican allotetraploid species stoloniferum (AABB was for extreme resistance viruses and late blight. In this study, genomic situ hybridization (GISH) visualization introgression material B subgenome S. into genome backcross hybrids. The fertile hexaploid hybrid ...
