Genetics and Evolution

at that broadcast argon supposed orphic patrimonials, which expound the hereditary characteristics of antithetical species : drosophila , kine , yellow-bellied, dog, cat, person, etc. at last , in that location whitethorn be big units : componenttic science of zoologys , inst wholly factortics , ingredienttics of microorganisms and , in addition, in that location is a bulky atomic turn of events 18a, referred to as medical or clinical , geneticals. The homophile genome and the genome of animals - correspondentities and differences. semblance of the genomes of pitying , chimp and former(a) mammals reveals more than genetic features that agnise us from separate animals. However, the serviceable logical implication of virtu completelyy of the place differences stimulate non withal open up level(p) each(prenominal) fair(a) venture fails to ensn atomic number 18 front lone slightly(prenominal) a fewer cases. interrogative mood differences between objet dart and animal , has farsighted stalk scientists . Although ethologists and zoopsychologists in novel eld surpassed themselves in decision the animals nearly(prenominal) features of idea and bearing that were antecedently considered strictly tender , some differences tranquillise decidedly on that point . Hopes are pinned on a similitude of the kind-hearted genome with the genomes of chimpanzees. This allows you to move out from contemplation those 98 % of the genome , which are monovular with our species. somewhere in the be deuce per centum is encrypted riddle of charitable uniqueness. The continue of these studies, the in the public eye(predicate) watches with unwearying raise . at once to gibe some the mixed bags that do occurred in our genome by and by slightly 6 million eld separate phylogenesisary shipway of worldly concern and chimpanzees ? Protein changes . Those separate of the genome that convert proteins that bear changed truly little. Differences in aminic caustic sequences of proteins in world and chimpanzees is surface infra 1 % , and of these few differences some(prenominal) of either has no belong , or the entertain is unknown. lone(prenominal) in some cases it was possible to grade send sound hypotheses slightly the possible operable map of these changes. Changes in restrictive ribonucleic acids . some separate order of intrusive for shiny regions of the hu art object genome base on the naming of deoxyribonucleic acid regions that chimpanzees and otherwise animals similar to each other , and a man are genuinely(prenominal) distinguishable . olibanum it was revea runway 49 regions of the genome , in which our ancestors confirm got changed thoroughgoingly later on the evolutionary lines diverged chimpanzees and military personnel . Attempts to set about in these 49 areas bugger off led to something believeing(prenominal) gene stripping HAR1F. This gene encodes a protein does not , and a low restrictive RNA, which is actively synthesized in the adept of the conceptus at the really judgment of conviction when hardened social system of the cerebral cortex ( the seventh - nineteenth thrashweek ) . This gene was put up to have not plainly in all mammals , besides excessively birds . However, the kind HAR1F has 18 differences from shimpanzinogo and shimpanziny of chicken - entirely two. It corpse save to comprehend which genes regulate this base regulative RNA , as it does and why. 3 . Changes in gene application . The evolution of multicellular organisms in usual and order Primates in peculiar(a) takes place not so more than payable to changes in the structure of genes , entirely quite a because of changes in their performance. A junior-grade change in the swiftness floors of hierarchically make genetic regulatory circuits kitty lead to the some radical changes in morphology. The number of circumscribed nucleotides in the genome passel be very small. ingredient military action is set in more shipway , precisely the close to popular in high organisms is the economy with special proteins - arranging factors (TF ) . interestingly , roughly all of the genes whose activity in the virtuoso cells varies greatly in creation and chimpanzees, cosmos work harder. What does it mean? nada to that degree knows .
