The combination of DNA and π-conjugated polyelectrolytes (CPEs) represents a promising approach to develop DNA hybridization biosensors, with potential applications for instance in the detection of DNA lesions and single-nucleotide polymorphisms. Here we exploit the remarkable optical properties of a cationic poly[3-(6'-(trimethylphosphonium)hexyl)thiophene-2,5-diyl] (CPT) to decipher the self-...

In a study of chromosome pairing, the basic nucleoproteins of meiotic cells of Loxa flavicolis, a tropical bug, are compared with asynaptic cells of the testis and somatic cells. The normal meiotic cells are found to differ markedly from the other kinds, while only slight differences are found between asynaptic and somatic nuclei.
The small basic protein encoded by the open reading frame adjacent to the terC site in the Bacillus subtilis chromosome and previously implicated in termination of the replication process was purified. Band retardation assays established that this protein (now called the replication terminator protein, encoded by the rtp gene) binds specifically to a 209-base-pair fragment of DNA within which t...
This summary lays out the basic science and methodology used in genetic testing that investigates historical population migrations and the ancestry of living individuals. The genetic markers used in this testing, and the distinction between Y-chromosome, mitochondrial and autosomes analysis, are explained and the shortcomings of these methodologies are explored.
The yeast Saccharomyces cerevisiae is the pre-eminent organism for the study of basic functions of eukaryotic cells. All of the genes of this simple eukaryotic cell have recently been revealed by an international collaborative effort to determine the complete DNA sequence of its nuclear genome. Here we describe some of the features of chromosome XII.

the karyotype of zagros tooth-carp, aphanius vladykovi (coad) has been investigated byexamining metaphase chromosomes spreads obtained from gill epithelial and kidney cells. the diploidchromosome number of this species was 2n=48. the karyotype consisted of 8 submetacentric and 40subtelocentric chromosomes (8sm+40 st). the arm number (nf) was 28. sex chromosomes werecytologically indistinguishab...
background and objectives: primary amenorrhea is not a disease but a symptom that may result from several quite different causes[nn1] . common hormonal cause of primary amenorrhea includes constitutional delay, hypothalamic –pituitary dysfunction, chronic systemic disease and absent ovarian function. the aim of this study was to estimate the incidence of the chromosomal abnormality referred for...
