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.
