Question

Which structural component is found in DNA but not in RNA? ribose deoxyribose phosphate group nitrogenous base

Answer 1

Uracil.
Adenine,guanine,cytosine and thymine are the nitrogenous bases in DNA.
In RNA there is uracil instead of thymine.

Hope it will help u.

Answer 2

Answer: The correct answer is Deoxyribose.

Deoxyribose is the pentose sugar which is present in the structure of DNA ( deoxyribonucleic acid) . It is named so because there is absence of oxygen group at the 2' position of the pentose sugar.

On the contrary, pentose sugar of RNA is simply named as ribose sugar. There is presence of oxygen at 2' position ( in th form of -OH)  in its structure.

Thus, the structural component which is found in DNA but not in RNA is deoxyribose.
