DNA is selected for genetic information compared to RNA because
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
It is stable
Double stranted compared to RNA
Two strands are complementary
I has genes
