The third hydrogen bond in a guanine–cytosine base pair (bottom) was missed in the 1953 description of DNA (top). Credit: ACADEMIC PRESS.

The universal genetic code relies on two hydrogen-bonded Watson–Crick base pairs that can form 64 triplet codons. This places a limit on the number of amino acids that can be encoded, which has ...

In addition to the standard Watson-Crick base pairs, there are also non-canonical base pairs that can form in certain situations. These include wobble base pairs, such as G-U and I-A (inosine-adenine) ...

Measuring forces in the DNA molecule First direct measurements of base-pair bonding strength Date: September 8, 2016 Source: Technical University of Munich (TUM) ...

Rather than hydrogen bonding to keep the two strands of DNA together, ... Their bacteria were using artificial base pairs. This is clearly an intermediate step in a much larger project.

The results indicate that the biology underlying pair bonding and parenting isn't purely dictated by the receptors for oxytocin, sometimes referred to as the "love hormone." ...
