Rampant Cheating by Pathogens?
Pathogenic bacteria often cooperate during infection. Communication through quorum sensing allows bacteria to coordinate gene expression in a population density–dependent manner; biofilm formation increases population resistance to hostand antibiotic-related stresses. Although such cooperative behaviors benefit pathogens at the population level, individual cells experience costs of cooperation....
متن کاملCheating Cheating Detectors
In this paper we present a new cheating technique that is successful at defeating cheating detectors and could become popular with students. The idea is to use obfuscating code transformations (such as those found in the SANDMARK tool) to apply a sequence of minor code transformations to a copied programming assignment. This purpose is to produce a copy that will defeat detection. We show that ...

متن کاملGEN1 promotes Holliday junction resolution by a coordinated nick and counter-nick mechanism
Holliday junctions (HJs) that physically link sister chromatids or homologous chromosomes are formed as intermediates during DNA repair by homologous recombination. Persistent recombination intermediates are acted upon by structure-selective endonucleases that are required for proper chromosome segregation at mitosis. Here, we have purified full-length human GEN1 protein and show that it promot...
