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…

Are viruses microRNAs? (2)

terrarium eco system

The role of microRNAs in cell type differentiation can be compared in the context of the role of viruses and mutations that cause cancer. Facts provide a basis for explaining the biological basis of epigenetically-effected cell type differentiation in species…

Thermodynamic constraints and ecological adaptations sans evolution

Physics

Relationship between protein thermodynamic constraints and variation of evolutionary rates among sites Excerpt: “…a two-variable model that combines stability and stress signi ficantly improves predictions. Therefore, both the overall stability [symbol] and the stress [symbol] seem to capture distinct thermodynamic constraints on…

Did parental love evolve separately in birds and mammals?

neuronal-plasticity

EDUCATION: SEXUALITY EDUCATION IN THE UNITED STATES Excerpt: Romantic (erotic) love, an important component of human reproductive and sexual behavior, has its origins in parenting behavior. In reptiles, there is neither parental care nor an affectionate or affiliative bond between…

Teeth evolved: a short misrepresentation

Genetic code

Teeth: a Very Short Introduction Description: Presents the story of teeth – from the earliest tooth-bearing fishes hundreds of millions of years ago through amphibians, reptiles and, ultimately, mammals Teeth are amazing – the product of half a billion years…

Stem cell memory is biophysically constrained (2)

translocated chromosome

If stem cell memory is biophysically constrained, by nutrient-dependent pheromone-controlled amino acid substitutions, we can expect to find experimental evidence that conserved molecular mechanisms link the basic principles of nucleosome retention in plants to nucleosome retention in mouse and human…

Seemingly futile cycles are not thermodynamically futile

Physics

Scientists discover an on/off switch for aging cells The switch controls the growth of telomeres, the timekeepers of cells September 19, 2014 Excerpt: Understanding how this “off” switch can be manipulated–thereby slowing down the telomere shortening process–could lead to treatments…
