DNA-free division
n page 993, Bucciarelli et al. report the first evidence that chromosomes are not always necessary for proper spindle assembly and cell division. The authors stumbled upon chromosome-independent cell division during a screen for meiosis mutants in Drosophila. Two of the mutants they identified, fusolo and solofuso , had chromosome segregation defects that led to secondary spermato-cytes lacking...

متن کاملCell - free DNA: بیومارکر نوین تشخیص آزمایشگاهی
به انواع مختلف اسیدهای نوکلئیک آزاد در پلاسما شامل قطعات DNA ژنومی،DNA میتوکندریایی، DNA و mRNA های ویروسی و همچنین انواع miRNA اصطلاحا Cell–free nucleic acid گفته می شود. بخش مهمی از این اسیدهای نوکلئیک آزاد در پلاسما را Cell–free DNA (cfDNA) تشکیل می دهد. cfDNA به صورت قطعاتی با وزن مولکولی حدود KB 21-0.18 در سرم یا پلاسمای افراد سالم و افراد مبتلا به بسیاری از بیماری ها قابل تشخیص هستند. ...
متن کاملExact Procedures for Envy-free Chore Division
We develop the rst explicit procedures for exact envy-free chore division for 4 or more players. We also give a simple 3-person procedure. Our 4-person moving-knife scheme and n-person discrete algorithm are accomplished by exploiting a notion of \irrevocable advantage" for chores, and are motivated by similar solutions for cake-cutting by Brams, Taylor, and Zwicker. We discuss the diierences b...
متن کاملTwo-player envy-free multi-cake division
We introduce a generalized cake-cutting problem in which we seek to divide multiple cakes so that two players may get their most-preferred piece selections: a choice of one piece from each cake, allowing for the possibility of linked preferences over the cakes. For two players, we show that disjoint envy-free piece selections may not exist for two cakes cut into two pieces each, and they may no...
