Forces of “Nature” (part 3)

Physics

Straight up, with a twist: New model derives homochirality from basic life requirements Excerpt:  In every living thing on Earth, all amino acids are left-handed, and all sugars are right-handed. Glycine is an achiral amino acid. It is the only…

De novo creation of olfactory receptor genes

terrarium eco system

Large-scale transcriptional profiling of chemosensory neurons identifies receptor-ligand pairs in vivo Reported as:  Deciphering the olfactory receptor code Excerpt: Its applications, countless, extend for example to the domain of chemicals able to trigger predetermined behaviors in mammals or in insects,…

Hiding things about neo-Darwinism

Genetic code

Biologists devise invasion plan for mutations Excerpt:  “…researchers describe a technique for creating mutations that invade the genome and transmit themselves across to the next generation with near 100% success, defying the classic laws of Mendelian genetics.” My comment: Placed…

Modeling conserved microRNA expression

translocated chromosome

Insects as models to study the epigenetic basis of disease Excerpt: “…selected insects can be used as models for human diseases with an epigenetic component because the underlying molecular mechanisms (DNA methylation, histone acetylation and the expression of microRNAs) are…

RNA-mediated.com (topic descriptions)

The life cycle of an mRNA in a eukaryotic cell RNA is transcribed in the nucleus processing, it is transported to the cytoplasm and translated by the ribosome. Finally the mRNA is degraded

Another companion domain has been added to the ScentofEros.com; Pheromones.com, PerfumingtheMind.com collection Intro to topics/catagories at RNA-mediated.com Information that links physics, chemistry, and molecular epigenetics from ecological variation to ecological adaptations via RNA-mediated events, such as the de novo creation…
