Which structural component is found in dna but not in rna?
a. ribose
b. deoxyribose
c. phosphate group
d. nitrogenous base

The correct option is B. Deoxyribose.

DNA is made up of small units called as dNTP ( deoxyribonucleoside triphosphate). In the dNTP, deoxyribose sugar, nitogenous base, and phosphate group is present. Deoxyribose is a pentose sugar, which contains Hydrogen group at 2' carbon of its pentose ring ( therefore called deoxyribose).

Whereas in RNA, OH ( hydroxyl group) is present at 2' carbon of the pentose ring. Therefore, it is not called deoxyribose.

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

answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;

option a and d is the correct answer

i hope this u

plz mark as the brainliest answer
