Detailed explanation-1: -In RNA, uracil binds to adenine via two hydrogen bonds. In DNA, the uracil nucleobase is replaced by thymine (T). Uracil is a demethylated form of thymine.
Detailed explanation-2: -Uracil (U) is one of the four nucleotide bases in RNA, with the other three being adenine (A), cytosine (C) and guanine (G). In RNA, uracil pairs with adenine. In a DNA molecule, the nucleotide thymine (T) is used in place of uracil.
Detailed explanation-3: -uracil, a colourless, crystalline organic compound of the pyrimidine family that occurs as a component of ribonucleic acid (RNA), a molecule involved in the transmission of hereditary characteristics.
Detailed explanation-4: -Adenine and Uracil bonding is a hydrogenous bonding between the two nucleobases. Adenine and Uracil both are complementary to each other and make hydrogenous double bonds between them and stabilize a RNA structure. This hydrogenous double bond between them is known as adenine and Uracil bond.
Detailed explanation-5: -DNA uses thymine and deoxyribose sugar, while RNA uses uracil and ribose sugar. While DNA is usually molded into a double-stranded helix, RNA is usually single-stranded, which allows for the binding of anticodons during translation.
