the 18s ribosomal dna sequence of strongyloides stercoralis in iran

background : strongyloides stercoralis is a prevalent parasite in some rural areas in the north of iran. we decided to investigate whether the 18s ribosomal dna sequence of the parasite in iran is similar to the findings of the other re­searchers. methods :  we collected 3514 stool samples from gilan and mazandaran, northern iran, during the year 2005-2006, from which 96 were found infected wit...

Mitochondrial DNA sequence-based phylogenetic relationship of Trichiurus lepturus (Perciformes: Trichiuridae) from the Persian Gulf

In this study, mitochondrial DNA analysis using 16S ribosomal DNA (rDNA) was performed to investigate the phylogeny relationship of Trichiurus lepturus in the Persian Gulf compared to the other investigated area. The amplification of 16S rDNA resulted in a product of 600 bp in all samples. The results showed that the isolated strain belongs to T. lepturus showing 42 divergence sites among the s...

A MODEL FOR THE BASIC HELIX- LOOPHELIX MOTIF AND ITS SEQUENCE SPECIFIC RECOGNITION OF DNA

A three dimensional model of the basic Helix-Loop-Helix motif and its sequence specific recognition of DNA is described. The basic-helix I is modeled as a continuous ?-helix because no ?-helix breaking residue is found between the basic region and the first helix. When the basic region of the two peptide monomers are aligned in the successive major groove of the cognate DNA, the hydrophobi...

Dna Sequence Evaluation Dna Sequence Evaluation Gc Content

• A DNA molecule consists of two strands, commonly referred to as top and bottom; positive and negative; or normal and reverse. The contents of one strand form a reverse complement of the other strand. The ”complement” part: A(denine) is always paired with Thymine, while Cytosine is always paired with Guanine. The ”reverse” part: the strand are read in opposite directions: the 5’ end of one str...
