Which of the following statements is correct?

RNA contains thymine Nucleosides do not contain phosphorous DNA is made of amino acids Adenine is a pyrimidine

Nucleosides do not contain phosphorous

Adenine is a substituted purine as it has two fused rings. DNA is made up of nucleotides. RNA does not contain thymine, instead it has uracil. Nucleosides have a base attached to a pentose sugar. Since both the sugar and base do not contain phosphorous, nucleosides do not have it. On the other hand, nucleotides contain phosphorous in the form of phosphoric acid.
