conclusions this study revealed allele frequency of some strs on chromosome 12 and 16 for the first time in iran, and indicated differences between subjects with metabolic syndrome and subjects in the control group. results there was no significant deviation in allelic frequencies from hardy-weinberg equilibrium for all the studied markers except for d12s1632 and d12s329. the long alleles in d1...

The success of the Human Genome Project (HGP) has provided a blueprint for the approximately 20,000 gene-encoded proteins potentially active in all of the hundreds of cell types that make up the human body. Yet we still have limited knowledge about a majority of the gene-encoded proteins which are the “building blocks of life” and “cellular machinery”. It is estimated that for nearly half of th...

The male-specific lethal (MSL) protein-RNA complex is required for X chromosome dosage compensation in Drosophila melanogaster. The MSL2 and MSL1 proteins form a complex and are essential for X chromosome binding. In addition, the MSL complex must integrate at least one of the noncoding roX RNAs for normal X chromosome binding. Here we find the amino-terminal RING finger domain of MSL2 binds as...

Genetic variations were studied for 13 accessions of Lolium multiflorum using cytogenetical traits. Karyotype was prepared for 5 metaphases cells of each accession and the traits of total length (TL), long arm (LA), short arm (SA), arm ratio (AR) and centromer index (CI) were determined by micromeasure software. Six accessions were diploid and seven accessions were tetraploid, the basic chromos...

Chromosome 'painting' refers to the hybridization of fluorescently labeled chromosome-specific, composite probe pools to cytological preparations. Chromosome painting allows the visualization of individual chromosomes in metaphase or interphase cells and the identification of both numerical and structural chromosomal aberrations in human pathology with high sensitivity and specificity. In addit...

Using cointegrate formation, we constructed a basic replicon of the megaplasmid/mini-chromosome pTAV3 of Paracoccus versutus UW1. It is composed of two adjacent modules, responsible for plasmid replication (rep) and partitioning (par). Functional analysis of the par region identified a determinant of incompatibility (inc2), whose presence is crucial for proper partitioning (the partitioning sit...

UNLABELLED The purpose of this work is to provide the modern molecular geneticist with tools to perform more efficient and more accurate analysis of the genotype data they produce. By using Microsoft Excel macros written in Visual Basic, we can translate genotype data into a form readable by the versatile software 'Arlequin', read the Arlequin output, calculate statistics of linkage disequilibr...

Cytological, seed and epidermal studies were carried out of 9 taxa belonging to 4 genera 6 species the tribe Eupatorieae. Chromosome counts 2 species-Adenostemma caffrum (n=10) A. mauritianum are reported for first time from Nigerian flora report Ageratum conyzoides (n=18) differed earlier reports. The cytotypes in is flora. pollen fertility test all plants studied high this revealed that meios...
