DNA is selected for genetic information compared to RNA because
It is stable
Double stranted compared to RNA
Two strands are complementary
I has genes
The presence of the oxygen atom in the 2nd carbon of RNA make it more prone to spontaneous hydrolysis DNA is much more stable, the half-life of spontaneous hydrolysis is about 200 million years The possibility of mutations occurring and remaining unidentified is more with uracil since cytosine can be easily deaminated to uracilRef: DM Vasudevan, 7th edition, page no: 576, boxes 44.1
