Answer 2

Answer:

surely RNA was first as if you observe the chemical composition of RNA and DNA, 'URACIL' U present in RNA where as THYMINE' 'T' is in DNA. sure u canclearly understant the difference between the U and T where the 5th position of U is filled with CH3 group by doing so it converted to T. Due to some mutations this change was happened. so, DNA came from RNA..... I think this explonation is an exact answer for your question.
