Which of the following is TRUE for RNA??
A
Contains ribose sugar
B
Contains uracil and not thymine
C
Contains phosphate group
D
All the above
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘A ≠ U, G ≠ C’.

Detailed explanation-2: -The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.

Detailed explanation-3: -In RNA, the nucleotide thymine is absent, but in its place is the nucleotide uracil. Uracil is able to base pair with adenine via two hydrogen bonds, but this only happens in RNA, not DNA! In DNA, thymine is present rather than uracil.

Detailed explanation-4: -RNA does not have double stranded -helix structure.
