However, the hetero-pair is the most strongly bound as only this host–guest complex is further stabilized through complementary hydrogen bonding between the nucleotides (Fig. 1).

The base pairing interactions between the complementary nucleobases contribute to the overall structure and stability of the DNA double helix. The hydrogen bonds between the base pairs, along with the ...

This pairing is very specific: adenine pairs with thymine and cytosine pairs with guanine. This selective pairing is called ‘complementary base pairing’. A-T pair forms two hydrogen bonds ...

DNA containing a new unnatural base pair may be amplified by PCR and transcribed into RNA, potentially increasing the diversity available from nucleic acids.

For another, there are what experts call base pair stacking forces, which act between the stacked base pairs along the spiral axis. The forces of the hydrogen bonds, on the other hand, act ...

This pairing occurs due to hydrogen bonds forming between complementary bases. In DNA, the bases are cytosine (C), thymine (T), adenine (A) and guanine (G). In double stranded DNA, A-T and C-G will ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

The two strands of the DNA helix are unzipped by breaking of the weak Hydrogen bonds between base pairs. This unwinding of the helix is caused by an enzyme (helicase enzyme).
