Which of the following is found in both dna and rna? a) ribose, phosphate groups, and adenine b) deoxyribose, phosphate groups, and guanine c)phosphate groups, guanine, and cytosine d)phosphate groups, guanine, and thymine

C) Phosphate groups, guanine and cytosine.

DNA ( deoxyribose nucleic acid) and RNA ( ribonucleic acid) are considered as the genetic material of different organisms.

DNA contains dNTP ( deoxyribonucleoside triphosphate) as monomeric unit, whereas RNA contains NTP ( ribonucleoside triphosphate) as the monomer. The nitrogenous base, a pentose sugar and phosphate group are present in both DNA and RNA.

DNA contains the following nitrogenous bases- Adenine (A), Guanine (G), Thymine (T), and Cytosine (C), whereas RNA contains Uracil (U) in place of Thymine.

Guanine and Cytosine are the nitrogenous bases found in both DNA as well as RNA. Thus, in the given question, answer C) is correct.
