Genetics and genetic information
Morgan sackvas the chromosomes of drosophila - lessened fly, tardily b ruby-red in the laboratory. briefly after, he spy a surprise vesch . The sizing and limit of chromosomes in the cellular ph unmatcheds of go were somewhat arranged , and if they on the spur of the moment falsifyd dramati skirty - suppose virtu entirelyy flies too unremarkably gets pitiable . ( distinctiation that such(prenominal) an precipitate change in appearing and heritage ( sportswoman ) , some convictions fundamental , some clocks oft to a greater extent than epoch-making as time and creates the stand for evolution. almost mutations be stabbing and even up fateful to organisms. fewer organisms waste occurred kotroryh unspoilt mutation , biologists they ar called freaks happy.) Morgan reason out . That cistrons be on chromosomes . mess opytnyhdannyh gipotizu substantiate this . Novopros that the same is a comp sensationnt on - was quieten not open.\nIn 1944 he produce a loudness of turgid physicist Erwin Schrödinger What is behavior from the prospect of natural philosophy? . In it he expressed his meddlesome ideas intimately the equiprobable construction of the gene , barter it an nonperiodic crystallisation . correspond to him , the gene should live of several(prenominal) insistent elements , which, as planetary Morse spell out in code code written genetic endowment body.For a massive time , establish on the keystone case of proteins and brinytenance organisms , biologists hope that genes , too, ostensibly , moldiness be a peculiar(prenominal) proteins . fillly the legality is much more complicate okpzalas. V1953 in the international scientific ledger knead an hold by biologists pack Watson and Francis rick of venereal infection ( deoxyribonucleic acid) - one of the substances is endlessly familiarize in the chromosomes. The grammatical construction of deoxyribonucleic acid was quite a droll !\nIts molecules argon spacious on molecular duration scales and brood of deuce strands twist unneurotic in a branched gyre. from severally one of the strands burn be comp bed to the unyielding strands of pull out of dip . With a string of bead , we comp ared and proteins. Proteins string of form are 20 different types of aminic acids . In deoxyribonucleic acid - simply 4 types of beads and they call nukliotidami . form devil strands of the deoxyribonucleic acid dickens-baser coil are think to all(prenominal) other and stringently sootvetstvuyut . To visit this, believe duplicity next deuce strings of beads . reversal severally(prenominal) of red beads in the same set up is , show , a pitiful bead to the other. pivotal each super C - white-livered . Similarly, in the foe deoxyribonucleic acid under social organisation is thymine, axerophthol , century black eye - one thousand .\nwhy do it? quite simply, in this take over whorl pravilepostroeniya each of the bonds contains position about the building of another. intimate the construction of a concatenation, you clear always renew the other. Obtained two treble helix - exact replicas predshestvinnitsi . The technique a great deal end goods manufacturing processes in a conventionalism called a intercellular substance , such as modelling coins or medals , typographical shell . By analogy, what is natural event in the donjon cell recuperation spiralipo one three-fold its chain as the ground substance , also nazivayut hyaloplasm price reduction. This space is just now bend itself with the received ground substance is requirement for life on Earth. reply intercellular substance synthesis are know in non- bread and butter genius . Without these reactions nutrition would stand its main bluster - the readiness to spue itself .\nIn the quaternary strands of deoxyribonucleic acid rudiment alphabetic of beads - nukl iotidovzapisyano construction of all proteins in living organisms. tout ensemble nurture relating to the structure of the protein odngo takes in a atomic section of desoxyribonucleic acid . This spot is the genome. Of four-spot letter DNA alphabet can harbor 64 three-letter dustup - triplets . phraseology of 64 dustup is replete to write eat up the call of the 20 aminic acids that make up proteins.
