CHROMOSOME CONTENT. "Proteins and RNAs determine a three-dimensional architecture of the chromatin complex of interphase chromosomes, which then controls DNA expression." https://lnkd.in/eeiUHXC View in LinkedIn

CAUSATION LOOPS. "The structural code reigns over the script code. In organisms, the upward (bottom-up) and downward (top-down) causations are inherently intertwined between numerous feedback interactions." https://lnkd.in/eeiUHXC View in LinkedIn

GENES ARE A PART BUT NOT ALL. "Claims that the ‘book of life’ is written in the genetic programme of the genome are not embracing the whole complexity of living organisms. The concept of genes as a symbolic representation of an organism— a code script—is not the whole story." https://lnkd.in/eeiUHXC View in LinkedIn

DNA-CENTRIC THINKING. "Discoveries about viruses, most of which do not use DNA but rather RNA as a code script, also highlight the non-centrality of DNA-based code script for living agents." https://lnkd.in/eeiUHXC View in LinkedIn

TOP-DOWN DIRECTION. "Agency, context, meaning, interpretation and behaviour are features of biological organization that can be independent of the DNA-based code script. In living organisms, these cognitive features feed back, in a top-to-bottom manner, into the DNA sequences." https://lnkd.in/eeiUHXC View in LinkedIn

CONSORTIAL AGENTS. "We have tried to exemplify the multiple roles of consortia of ribozymatic agents emerging from compatible stem-loop structures that work together to build RNA viruses and create infection-derived noncoding RNA networks without which life cannot function." https://lnkd.in/eUYvi8e View in LinkedIn

MODULAR FUNCTIONALITY. "The basic behavioral competences of these agents are absent in inanimate nature and resemble core sets of behavioral rules that are fundamentally shared by RNA agents but yet may change or adapt to varying adaptational purposes. This explains their module like character." https://lnkd.in/eUYvi8e View in LinkedIn

FRAGMENT FROM NATURE continues for a second weekend on the subject of parasite-host relationships. This weekend focuses somewhat on host reactions and defenses, as well as the gene targets within hosts for the parasites. For humans, it takes sophisticated research labs to find gene targets. For nature, it takes millions of years of evolution by trial and error. View in LinkedIn

WHY NATURE. "The more I study nature, the more I become impressed […] that the contrivances and beautiful adaptations [acquired through natural selection] transcend in an incomparable degree [those] which the most fertile imagination of the most imaginative man could suggest with unlimited time at his disposal." (Charles Darwin). https://lnkd.in/eykUy37 View in LinkedIn

PLEASE EAT MY HOST. "Infection by the parasite Pomphorhynchus laevis leads to altered drifting behavior in Gammarus pulex, an intermediate host of P. laevis. This altered behavior increases G. pulex’s predation risk by P. laevis’s definitive host. The induced behavioral alteration in the host thus leads to the parasite’s increased success in completing its life cycle." https://lnkd.in/e4MsheB View in LinkedIn
