Explanation:
Detailed explanation-1: -Uracil is found only in RNA and not in DNA.
Detailed explanation-2: -Correct answer: Uracil is a nitrogenous base that is only found in single-stranded RNA-it is not found in DNA.
Detailed explanation-3: -Sugar. Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).
Detailed explanation-4: -ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.
