Study Notes

Central Dogma of Molecular Biology

  • The central dogma states that information is transferred from nucleic acid to protein, but not from protein to nucleic acid.
  • The central dogma was first stated by Francis Crick.
  • The central dogma was first published in 1970 in a Nature paper by Francis Crick.
  • The central dogma describes the transfer of information from nucleic acid to protein as a one-way process.
  • According to Francis Crick, once information has passed into protein, it cannot be transferred back to nucleic acid.
  • The central dogma defines "information" as the sequence of nucleotides in DNA or RNA that encodes the genetic instructions used in the development and function of an organism.
  • The original meaning of the central dogma is that genetic information flows from DNA to RNA to proteins, but not in the reverse direction.
  • The central dogma accurately describes the process of gene expression, where genetic information is used to synthesize proteins.

Test your knowledge of the central dogma of molecular biology with this quiz! Explore the flow of genetic information from DNA to RNA to protein and discover the original meaning behind Francis Crick's groundbreaking theory. Challenge yourself and see if you can grasp the concept that once information has become protein, it cannot be reversed.
