BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions.

Detailed explanation-3: -Both DNA and RNA consists of polymers of nucleotides. RNA is single stranded but DNA is double stranded. DNA polynucleotide contains thymine but RNA polynucleotide contains uracil.

Detailed explanation-4: -So it is protected from oxygen in the nucleus. Outside of the nucleus, it is quickly destroyed. Uracil is resistant to oxidation and is utilized in RNA, which exists outside of the nucleus. Compared to RNA, DNA is more stable.

Detailed explanation-5: -Explanation: Uracil is only found in RNA under normal conditions. It replaces thymine, which is only found in DNA. Therefore, thymine, adenine, cytosine, and guanine are the bases found in DNA, and uracil, adenine, cytosine, and guanine are the bases found in RNA.
