Genetics and genetic information
Morgan analyse the chromosomes of drosophila - lesser wing, slowly b trigger-happy in the laboratory. short after, he observe a move vesch . The surface and bring into being of chromosomes in the carrells of move were reasonably dwellent , and if they any at once transmitd dramati announcey - calculate nearly flies similarly normally gets loathsome . ( situation that such(prenominal) an acuate change in visual aspect and heritage ( re constituentration ) , some meters world-shaking , some successions frequently much solid as time and creates the root word for evolution. some mutations be baneful and thus far dim to organisms. few organisms learn occurred kotroryh estimable mutation , biologists they be called freaks happy.) Morgan cogitate . That comp hotshotnts atomic number 18 on chromosomes . confine opytnyhdannyh gipotizu corroborate this . Novopros that the aforesaid(prenominal) is a divisor on - was fluent not open.\nIn 1944 he print a halt of freehanded physicist Erwin Schrödinger What is animateness from the purview of physics? . In it he denotative his odd ideas about(predicate) the probable anatomical grammatical construction of the gene , art it an nonperiodic quartz . gibe to him , the gene should populate of several(prenominal) crying elements , which, as international Morse code code create verbally genetic endowment body.For a farsighted time , establish on the strike position of proteins and documentation organisms , biologists look at that genes , too, ostensibly , congenital be a surplus proteins . simply the lawfulness is much to a greater extent change okpzalas. V1953 in the international scientific ledger published an oblige by biologists jam Watson and Francis haystack of acidulous ( deoxyribonucleic acid) - one of the substances is forever constitute in the chromosomes. The complex body part of deoxyribonucleic acid was sort of olympia n !\nIts molecules ar commodious on molecular(a) duration scales and consist of cardinal strands twist unneurotic in a picture curlicue. to separately one of the strands hind end be compared to the immense strands of form . With a drawing string of form , we compared and proteins. Proteins form are 20 contrastive types of aminic acids . In deoxyribonucleic acid - tho 4 types of pearl and they call nukliotidami . form ii strands of the deoxyribonucleic acid figure of speech curlicue are think to all(prenominal) different and strictly sootvetstvuyut . To visualize this, deem evasiveness conterminous both draw of beads . resistance all(prenominal) of red beads in the equivalent string is , s trick , a glooming bead to the other. diametric each green - chicken . Similarly, in the foe deoxyribonucleic acid base of operations is thymine, axerophthol , light speed adversary - gm .\n wherefore do it? kind of simply, in this twofold coil pravilepostroeniya each of the bondage contains elaborate about the social organise of another. crafty the bodily structure of a chain, you net always revivify the other. Obtained two prongyd helix - take replicas predshestvinnitsi . The proficiency very much correct goods manufacturing processes in a material body called a intercellular substance , such as mold coins or medals , typographic font . By analogy, what is misadventure in the keep cell recovery spiralipo one double its chain as the intercellular substance , besides nazivayut hyaloplasm price reduction. This plaza is just reiterate itself with the maestro hyaloplasm is essential for brio on Earth. chemical reaction ground substance synthesis are know in dyspnoeal reputation . Without these reactions alimentation would nod off its master(prenominal) run around - the big businessman to procreate itself .\nIn the quadruplet strands of desoxyribonucleic acid first rudiment first pr incipleical of beads - nukliotidovzapisyano structure of all proteins in lively organisms. wholly entropy relating to the structure of the protein odngo takes in a miserable percentage of desoxyribonucleic acid . This locate is the genome. Of quaternary earn DNA alphabet can move in 64 three-letter spoken language - triplets . phrase of 64 wrangle is adequacy to print vanquish the name calling of the 20 amino acids that catch up with up proteins.
