  • The chemical method for deciphering the genetic code was developed by Har Gobind Khorana.
  • This was instrumental in synthesising RNA molecules with a defined combination of bases while the cell-free protein synthesis system developed by Marshall Nirenberg ultimately contributed to the decipherment of the code.
