It has three main distinct types.

Detailed explanation-1: -All of the following are true about RNA, except: RNA is not a double-helix RNA has thymine as a base. RNA does not contain deoxyribose RNA has Uracil as a base In RNA, Cytosine and Guanine are base pairs.
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. RNA is synthesized from DNA by an enzyme known as RNA polymerase during a process called transcription.
Detailed explanation-3: -So, the correct option is ‘RNA contains ribose. ‘
Detailed explanation-4: -RNA does not have double stranded -helix structure.
Detailed explanation-5: -Answer and Explanation: The correct answer is B. All of the given statements are true about RNA, except that RNA has thymine as a base. Ribonucleic acid or RNA consists of phosphate, ribose sugar, and a nitrogenous base that can be a purine (adenine or guanine) or a pyrimidine (cytosine or uracil).
