Detailed explanation-1: -Uracil is unique in RNA. It is not found 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: -Uracil is unique in RNA. It is not found in DNA. Instead of uracil in DNA, thymine is present.
Detailed explanation-4: -The four bases of DNA are adenine, thymine, cytosine, and guanine, abbreviated A, T, C, and G respectively. In RNA, the base thymine is not found and is instead replaced by a different base called uracil, abbreviated U. The other three bases are present in both DNA and RNA.
Detailed explanation-5: -DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose. Polynucleotides are formed by covalent linkages between the phosphate of one nucleotide and the sugar of another, resulting in phosphodiester linkages.
