Central Dogma is

In 1958  Crick  proposed  that  the  information  present  in  DNA  (in  the  form  of  base sequences)  is  transferred  to  RNA (the process is called transcription) and  then  from RNA  it  is  transferred  to  proteins  in  the form  of  amino-acid  sequence (called translation)  and  that  this  information  does  not  flow  in  the  reverse direction  i.e.  from protein  to  RNA  to  DNA.  This relationship between  DNA,  RNA  and protein  is  known  as  central  dogma.
