REGIONAL MOLECULAR EVOLUTION. "Because organisms vary widely in genome GC content in a manner consistent with directional mutation pressure, we might expect the different parts of the RNA molecule to change in composition at different rates due to the different selective constraints in different regions, just as the three reading frames within mRNAs change in composition at different rates that reflect the average effect of mutations in each frame." https://lnkd.in/erj2nzZ View in LinkedIn

PRE-COORDINATED NETWORKS. "Viral quasispecies as precoordinated networks of integrating agents brought Alu. The integration of infecting agents into host genomes is not a randomly occurring process but needs the features and competences of consortia of RNA stem loops, that is, what Eigen termed quasispecies populations." https://lnkd.in/eUYvi8e View in LinkedIn

"ALU ELEMENTS alone are estimated to have inserted into 75% of all human genes." https://lnkd.in/eUYvi8e View in LinkedIn

PARTS OF A WHOLE. "In current biology, a network (eg, the nodes in the net) is not evaluated from the perspective of agents. Individual participants are simply “inert” nodes in an interacting net. Proteomes, transcriptomes, and interactomes are all more or less presented as such simple collections in a systems biology view of such ensembles." https://lnkd.in/eUYvi8e View in LinkedIn

"RNA STEM-LOOP SWARMS and viral quasi-species. RNA social membership is essential but basically indefinable." https://lnkd.in/eUYvi8e View in LinkedIn

FRAGMENT FROM NATURE for the next two weekends looks at the remarkable extent to which parasites can control their host's behaviors, often totally changing it to further the success and life cycle of the parasite. The biochemical mechanisms underlying the parasitic control, and the types of host defenses are quite intriguing. But more, it shows how deeply parasites can hack their hosts. View in LinkedIn

"PARASITES often have profound effects on the animal hosts they invade by affecting development, physiology, morphology, evolution and ecology. In many cases, host behaviour is also altered upon parasitic infection. These changes range from slight alterations of already existing behavioural traits to the exhibition of completely new activities." https://lnkd.in/e4DPgex View in LinkedIn

"PARASITIC INFECTIONS are often followed by changes in host behaviour. Numerous and exquisite examples of such behavioural alterations are known, covering a broad spectrum of parasites and hosts." https://lnkd.in/eMBtiKq View in LinkedIn
