Human-specific gene ARHGAP11B promotes basal progenitor amplification and neocortex expansion Excerpt: “…the C-terminal 47 amino-acids of ARHGAP11B (after lysine-220) constitute not only a unique sequence, resulting from a frameshifting deletion (fig. S10), but also are functionally distinct from their counterpart…

 Evolutionary resurrection of flagellar motility via rewiring of the nitrogen regulation system Excerpt: The fast-spreading strain AR2F had acquired an additional point mutation in the σ54-dependent EBP gene ntrC, which alters an amino acid (R442C) within the DNA binding domain…

Let there be anti-entropic light (1)

terrarium eco system

Summary: Light-induced amino acid substitutions link cell type differentiation in plants to nutrient-dependent pheromone-controlled reproduction in animals via the biophysically constrained chemistry of protein folding. Protein folding is perturbed by mutations that limit the ability of organisms to adapt to…

See also: An epigenetic trap (the sequel) Excerpt: “Support for the link from one epigenetic trap to cell type differentiation was included in the molecular epigenetics section of our 1996 review, which detailed how RNA-mediated chromatin remodeling occurs.” My comment:…

1) Arguments in the evo-devo debate: say it with flowers! Abstract excerpt: A key question in evolutionary developmental biology is how DNA sequence changes have directed the evolution of morphological diversity. The widely accepted view was that morphological changes resulted…

Atoms to ecosystems is not almost a molecular ecology

terrarium eco system

In Kohl (2012) I wrote: Among different bacterial species existing in similar environments, DNA uptake (Palchevskiy & Finkel, 2009) appears to have epigenetically ‘fed’ interspecies methylation and speciation via conjugation (Fall et al., 2007; Finkel & Kolter, 2001; Friso &…
