Question

which structural component is found in dna but not in rna?
ribose
deoxyribose
phosphate group
nitrogenous base

Explanation:

• DNA (deoxyribonucleic acid) contains deoxyribose sugar.
• RNA (ribonucleic acid) contains ribose sugar.
• Both DNA and RNA have phosphate groups and nitrogenous bases (though RNA has uracil instead of thymine in DNA for one of the nitrogenous bases, but the question is about a structural component not present in RNA which is related to the sugar).

Answer:

deoxyribose
