A:

Hi Srishti,

RNA was the first genetic material in the cell because:

  1. RNA is capable of both storing genetic information and catalyzing chemical reactions.
  2. Essential life processes such as metabolism, translation, splicing, etc.  evolved around RNA.
  3. RNA  has the tendency of self replication.
