Chargaff discovered that in DNA, there is a 1:1 ratio of adenine and thymine, and a 1:1 ratio of guanine and cytosine. This led to the rule that adenine always pairs with thymine and guanine always pairs with cytosine.

If there are 12 nucleotides, the number of mRNA codons can be calculated by dividing the total number of nucleotides by 3, since each codon consists of 3 nucleotides. Therefore, with 12 nucleotides, there would be 12 / 3 = 4 codons.
nucleotides
The sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
The American biochemist Erwin Chargaff discovered that DNA is the primary constituent of the gene, thereby helping to create a new approach to the study of the biology of heredity.
because the discover
James Watson and Francis Crick discoverd the two strands of nucleotides that form a twisted ladder (double helix) in DNA
Basically chargoffs rule, of i all know, Thymine equals the Adenine, Cytosine equals the Guanine, and something else about the pyrmine. - nikkiYes, Nikki is close and she has the right idea. Erwin Chargraff, an American biochemist, had discovered that the percentages of guanine (G) and cytosine (C) bases are almost equal in any sample of DNA. But the same thing is true for the other nucleotides, adenine (A) and thymine (T). (A) = (T) and (G) = (C) became known as Chargraff's rules. - bradberrya
the two strands of nucleotides twisting around a central axis.
Yes, nucleotides pair with specific complementary nucleotides based on their chemical properties.
Thymine is found on DNA nucleotides but not on RNA nucleotides. In RNA, thymine is replaced by uracil.
Purine nucleotides differ from pyrimidine nucleotides in their structure due to the number of nitrogen-containing rings they have. Purine nucleotides have a double-ring structure, while pyrimidine nucleotides have a single-ring structure.

DNA nucleotides. Note that adenine, thymine, cytosine and guanine are NOT nucleotides, but they are only the bases which make the nucleotides different.
