What makes DNA different from RNA?
A
they type of phosphate
B
the type of sugar
C
having C pair with G
D
Having A’s
Explanation: 

Detailed explanation-1: -There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Detailed explanation-2: -Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation.

Detailed explanation-3: -While the DNA contains the deoxyribose sugar part, RNA contains the normal ribose sugar where each carbon (of the sugar part) is attached to exactly one carbon atom.
