As pointed out by Watson and Crick, the structure of DNA is central to its function, namely its duplication and its expression of the information contained in its nucleotide sequence. Thus ...

First, he noted that the nucleotide composition of DNA varies ... that A bound to T and C bound to G within the molecular structure of DNA (Figure 2). Chargaff's realization that A = T and C ...

Pseudouridine is an isomer of uracil, meaning it has the same chemical formula but a different structure. It is often referred to as the "fifth nucleotide" due to its abundance in RNA. Pseudouridine ...
