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.

if you look up in the top right corner you'll see your current profile picture, click than click "view profile" you'll be able to change it there.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
