Why There Are No Essential Genes on Plasmids.
Mobile genetic elements such as plasmids are important for the evolution of prokaryotes. It has been suggested that there are differences between functions coded for by mobile genes and those in the "core" genome and that these differences can be seen between plasmids and chromosomes. In particular, it has been suggested that essential genes, such as those involved in the formation of structura...

The air-filled tracheal respiratory system of insects prevents them from diving deeply in water. It is argued that this is the major factor in preventing insects from colonizing the open sea: they cannot descend sufficiently deeply in the daytime to escape being eaten by fish.
متن کاملWhy There Is No Statistical Test for Confounding, Why Many Think There Is, and Why They Are Almost Right
Confounding is a simple concept. If we undertake to estimate the e ect of one variable (X) on another (Y ) by examining the statistical association between the two, we ought to ensure that the association is not produced by factors other than the e ect under study. The presence of spurious association, due for example to the in uence of extraneous variables, is called confounding as it tends to...
متن کاملThere are no Aspects
In this paper, we claim that a specialized aspect module is not required. Instead, we propose an expressive aspect-oriented composition mechanism which can be applied upon existing modules. At the design level, the CoCompose modeling framework is introduced which is based on Model Driven Development. CoCompose allows step-wise refinement from a high-level design to the lowest level design or co...
متن کاملWhy are there deadly drugs?
Some drugs eventually have to be removed from the market because of a negative benefit-to-harm ratio, including an excess of mortality. Drug safety is the result of multiple factors, commencing with how clinical trials are designed, the information generated by and/or hidden through these trials, trial analysis by drug regulatory authorities (DRAs) and the amount of information that DRAs choose...
