Restriction-map variation associated with the G6PD polymorphism in natural populations of Drosophila melanogaster.
Restriction-map variation was studied in 126 copies of the G6pd region in X chromosome lines of Drosophila melanogaster from North America, Europe, and Africa. Special attention was focused on the distribution of variation relative to the geographically variable polymorphism for two electrophoretic variants. Nucleotide heterozygosity as determined by eight six-cutter restriction enzymes for the...
متن کاملRestriction-map variation in the Notch region of Drosophila melanogaster.
A worldwide sample of 37 X chromosomes of Drosophila melanogaster was analyzed with four restriction endonucleases for a 60-kb region of the Notch locus. Any two randomly chosen homologous chromosomes were heterozygous at one in 143 nucleotides (theta = 0.007). The chromosomes that were sampled contained no more than one insertion/deletion. The four insertions and one deletion observed in the 3...
متن کاملEnzymatic studies with the suppressor of vermilion of Drosophila melanogaster.
UPPRESSION is the complete or partial restoration of the wild-type phenotype by one gene in the presence of another nonallelic mutant gene that alone causes a mutant phenotype. Intragenic “suppressors” have also been reported (CRICK, BARNETT, BRENNER and WATTS-TOBIN 1961; HELINSKI and YANOFSKY 1963) but the term “second site reversion” used by HELINSKI and YANOFSKY seems useful in distinguishin...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولNaturally occurring variation in the restriction map of the amy region of Drosophila melanogaster.
The restriction maps of 85 alleles of the Amy region of Drosophila melanogaster from natural populations were surveyed. A subset of these were also scored for allozyme phenotype and adult enzyme activity of alpha-amylase. Large insertions were found in 12% of the alleles in a 15-kb region surrounding the two transcriptional units of the duplicated Amy locus. The low frequencies at which each of...
