These bases form complementary base pairs consisting of one purine and one pyrimidine, with adenine pairing with thymine, and cytosine with guanine. Guanine and cytosine bonded base pairs are stronger then thymine and adenine bonded base pairs in DNA. In RNA, the thymine is replaced by uracil (U). These bases pair with bases on the complemenatry strand according to the Watson and Crick base pairing ( A=T, G C ). Answer (1 of 3): So if a molecule has 30% Guanine then it will contain 30% of Cytosine as well. Bases pair off together in a double helix structure, these pairs being A and T, and C and G. RNA doesn't contain thymine bases, replacing them with uracil bases (U), which pair to adenine 1.

Miss Crimson: Yes, Professor, I'm sure DNA transcription is very interesting, but let's stick to the basic characteristics of DNA that pertain to the trial at hand. The AT pairing is based on two hydrogen bonds, while the CG pairing is based on three. The electronegative atoms involved in these hydrogen bonds are the oxygens and nitrogens found in the nitrogenous bases. Strict rules govern the complementary pairing, which Erwin Chargaff first discovered in 1949 and are called Chargaff's Rules in his honor. adenine. The pairing nature of DNA is useful because it allows for easier replication.

Polynucleotide Chain Structure & Overview | How do Nucleotides Link Together? Thymine Structure & Function| What is Thymine? The Journal of Organic Chemistry 2003, 68 (11) , 4439-4445. Adenine pairs with uracil in RNA molecules (e.g., when the rRNA codons pair with tRNA anti-codons in translation or when DNA is transcribed into RNA). These base-pairing rules ensure that, given the sequence of one strand of DNA (e.g., GATAGGA), the complementary sequence of the opposing strand can be determined (in this case, CTATCCT). Nucleotides are phosphate esters of nucleosides, and the nucleic acids (DNA and RNA) are high molecular weight polymers formed from long chains of four kinds of nucleotide units, which in DNA are derived from adenine, guanine, thymine, and cytosine.
