Which of the following is true regarding the structural and functional differences between DNA and RNA?
- RNA is more susceptible to alkaline hydrolysis because of the 2'-hydroxyl group on the ribose sugar.
- RNA typically exists as a double-stranded helix to protect the genetic information.
- DNA contains uracil, while RNA contains thymine to improve stability.
- DNA synthesis occurs in the 3' rightarrow 5' direction, whereas RNA synthesis occurs 5' rightarrow 3'.
