Expansion of Interstitial Telomeric Sequences in Yeast.
Telomeric repeats located within chromosomes are called interstitial telomeric sequences (ITSs). They are polymorphic in length and are likely hotspots for initiation of chromosomal rearrangements that have been linked to human disease. Using our S. cerevisiae system to study repeat-mediated genome instability, we have previously shown that yeast telomeric (Ytel) repeats induce various gross ch...
متن کاملMicrosatellite primers in the weedy annual herb Anacyclus clavatus (Asteraceae) and four closely related species1
UNLABELLED PREMISE OF THE STUDY Nuclear microsatellite primers were developed for the weedy herb Anacyclus clavatus to study the genetic structure of hybrid zones with closely related taxa in the western Mediterranean Basin, where different floral phenotypes are present. • METHODS AND RESULTS We obtained two microsatellite libraries using next-generation sequencing and Sanger sequencing of...

پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
Coevolution of telomeric repeats and telomeric repeat-specific non-LTR retrotransposons in insects.
In the telomeres of the silkworm Bombyx mori, telomeric repeat-specific non-long terminal repeat (LTR) retrotransposon SARTBm1 is accumulated in the TTAGG telomeric repeats. Here, we identify novel telomeric repeat-specific non-LTR retrotransposons, SARTTc family, from the red flour beetle Tribolium castaneum in the unconventional TCAGG telomeric repeats. To compare the sequence specificity of ...
متن کاملTelomeric repeats act as nucleosome-disfavouring sequences in vivo
Telomeric DNAs consist of tandem repeats of G-clusters such as TTAGGG and TG1-3, which are the human and yeast repeat sequences, respectively. In the yeast Saccharomyces cerevisiae, the telomeric repeats are non-nucleosomal, whereas in humans, they are organized in tightly packaged nucleosomes. However, previous in vitro studies revealed that the binding affinities of human and yeast telomeric ...
