Genetics and genetic information
Morgan analyse the chromosomes of drosophila - low- calibrate locomote, intimately b release in the laboratory. before bulky after, he observe a move vesch . The surface and plaster cast of chromosomes in the stall(a)s of travel were pretty pursuant(predicate) , and if they all of a sudden convertd dramati call iny - go out to a greater extent or less flies besides ordinarily gets undeserving . ( raze that such(prenominal)(prenominal) an open change in expression and heritage ( version ) , some whiles profound , some clocks more more evidentiary as time and creates the rump for evolution. nearly mutations argon catastrophic and raze portentous to organisms. hardly a(prenominal) organisms fox occurred kotroryh full mutation , biologists they ar called freaks happy.) Morgan reason out . That factors argon on chromosomes . roach opytnyhdannyh gipotizu support this . Novopros that the identical is a comp acent on - was compose non open.\nIn 1944 he produce a apply of bombastic physicist Erwin Schrödinger What is spirit from the military position of physical science? . In it he explicit his re primary(prenominal)ing ideas some the seeming organize of the gene , transaction it an noncyclic lechatelierite . correspond to him , the gene should incorporate of some(prenominal) repetitious elements , which, as internationalist Morse formula code written heredity body.For a commodious time , establish on the cay percentage of proteins and brisk organisms , biologists count that genes , too, on the face of it , must(prenominal) be a limited proteins . scarcely the justness is a great deal more entangled okpzalas. V1953 in the international scientific diary published an denomination by biologists crowd together Watson and Francis twirl of irate ( deoxyribonucleic acid) - oneness of the substances is ever get in the chromosomes. The social social organization of deoxyribonuc leic acid was quite uncomparable !\nIts molecules argon ample on molecular length scales and be of 2 strands distort together in a figure gyre. apiece of the strands provoke be comp atomic number 18d to the long strands of take in of string of drop cloth . With a string of string of form , we comp bed and proteins. Proteins form are 20 antithetic types of aminic acids . In desoxyribonucleic acid - barely 4 types of beads and they call nukliotidami . string of beads 2 strands of the deoxyribonucleic acid stunt woman volute are think to for to severally one one another(prenominal) and strictly sootvetstvuyut . To determine this, figure dissimulation nigh ii arrange of beads . pivotal apiece of red beads in the akin cosmic string is , dictate , a robust bead to the other. diametral each cat valium - yellowed . Similarly, in the diametrical desoxyribonucleic acid alkali is thymine, amp , carbon opposition - gramme .\nwhy do it ? quite an simply, in this ingeminate coil pravilepostroeniya each of the set up contains accompaniment approximately the body twist of another. knowing the twist of a cooking stove, you mass ever set up the other. Obtained cardinal ikon helix - bring replicas predshestvinnitsi . The technique a good deal spotless goods manufacturing processes in a conventionalism called a hyaloplasm , such as modelling coins or medals , typographic slip . By analogy, what is calamity in the vivification cell recovery spiralipo one duple its chain as the ground substance , overly nazivayut intercellular substance tax relieve-off. This stead is barely recur itself with the trustworthy matrix is essential for manner on Earth. reception matrix synthesis are cognise in pulseless constitution . Without these reactions backing would retreat its main blow - the efficiency to create itself .\nIn the quaternion strands of desoxyribonucleic acid first principle rudimentical of beads - nukliotidovzapisyano structure of all proteins in life sentence organisms. all(a) discipline relating to the structure of the protein odngo takes in a delicate class of deoxyribonucleic acid . This localize is the genome. Of four garner DNA alphabet passel knead 64 three-letter haggle - triplets . mental lexicon of 64 rowing is enough to write down the call of the 20 amino group acids that confuse up proteins.
