Which of the above statements regarding the components and pairing rules of nucleic acids are correct? S1: In DNA, the complementary base to cytosine is guanine, forming three hydrogen bonds. S2: The sugar in DNA is ribose, which contains an additional -OH group at the 2' position compared to deoxyribose. S3: Uracil is a pyrimidine base found exclusively in RNA, replacing thymine. S4: Adenine and Guanine are purines present in both DNA and RNA. S5: The stability difference between DNA and RNA is partly attributed to RNA being less reactive due to the absence of a 2'-OH group.
