USE OF VECTORETTE AND SUBVECTORETTE PCR FOR THE ISOLATION OF TERMINAL SEQUENCES FROM Y EAST ARTIFICIAL CHROMOSOME (YAC) CLONES
Development of yeast artificial chromosome (Y AC) vectors, molecular cloning of large segments of chromosomal DNA, and their propagation in yeast cells has become feasible. Overlapping Y AC provides a route to the development of physical maps of entire mammalian chromosomes. A rapid method was developed to isolate and sequence termini of Y AC inserts quickly. The Y AC clone is digested wit...
متن کاملRepetitive DNAs and shrink genomes: A chromosomal analysis in nine Columbidae species (Aves, Columbiformes).
An extensive karyotype variation is found among species belonging to the Columbidae family of birds (Columbiformes), both in diploid number and chromosomal morphology. Although clusters of repetitive DNA sequences play an important role in chromosomal instability, and therefore in chromosomal rearrangements, little is known about their distribution and amount in avian genomes. The aim of this s...
متن کاملMEIOTIC STUDIES OF SOME AVENA SPECIES AND POPULATIONS IN IRAN
Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. lud...
متن کاملMicrosatellite Isolation and Characterization in Pomegranate (Punica granatum L.)
Development of microsatellite markers has been an increasing trend in crop genetic studies because oftheir applicability in breeding programs. Here we report the development of inter simple sequencerepeat (SSRs) in pomegranate (Punica granatum L.) using an enrichment method that makes use of magneticbeads. Enriched genomic libraries with AG and ATG microsatellite motifs were c...
متن کاملChromosomal Abnormalities in Regions 8q22 and 13q32 Associated with Different Disorders in an Iranian Family
Chromosomal abnormalities are major causes of infertility, miscarriage and birth of handicapped progeny. In human live births, the prevalence of a chromosome aberration is ?0.5% and, of these, 0.1–0.3% correspond to structural chromosome rearrangements such as translocations, inversions, insertions and deletions .Our proband is an infant who had died 4 hours after birth due to a variety of abno...
