@ paras
RNA serves as both enzyme and genetic material early in evolution.. 
later, protein resumed the enzyme fucntion and RNA serves as genetic material only.. 
Proof: RIBOZYMES, these are the RNA serving as enzymes. 
amino acid polymerization was carried out by RNA working as enzymes. 
HOPE IT WILL CLEAR YOUR DOUBT THAT HOW PROTEIN CAME INTO EXISTANCE .. 
ALL THE BEST ./..

Then why didn’t RNA continued it’s job what was the reason for making protein and if it made protein from where did it get information from (that this particular protein can be made i have a specific sequence)
