Most of the research papers in random graph theory concern the Erdős–Rényi model 𝒢p, in which each edge is independently chosen with probability p for some given p > 0 (see ref. 3). In such random ...

In this report we address the molecular mechanisms by which elevated eIF2 phosphorylation controls mouse ATF4 expression. We find that the two uORFs contribute differentially to ATF4 translation.

Current efforts to reconstruct the tree of life and histories of multigene families demand the inference of phylogenies consisting of thousands of gene sequences. However, for such large data sets ...
Gene expression is a stochastic, or “noisy,” process. This noise comes about in two ways. The inherent stochasticity of biochemical processes such as transcription and translation generates “intrinsic ...
