Detailed explanation-1: -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-2: -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-3: -RNA contains ribose (pentose) sugar.

Detailed explanation-4: -Solution : RNA has ribose (as sugar) and uracil (a pyrimidine base). DNA has deoxyribose (as sugar) and does not contain uracil. Instead it contains thymine (as a pyrimidine base).

Detailed explanation-5: -RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.
