base pairing

[′bās ′per·iŋ]
(cell and molecular biology)
The hydrogen bonding of complementary purine and pyrimidine bases-adenine with thymine, guanine with cytosine-in double-stranded deoxyribonucleic acids or ribonucleic acids or in DNA/RNA hybrid molecules.

The error rates for natural base pairing by proofreading-deficient DNA polymerases (without 3'-exonuclease activity) range from [10.
Base pairing complementarity in polymerase reactions
Among these unnatural base pairs, the order of the efficiency and selectivity of the unnatural base pairing in T7 transcription is v-y > s-y > x-y.
Although the 98% selectivity of the unnatural base pairing is not sufficient for practical use in replication (the retention rate of the isoG-isoC pair in 20-cycle PCR amplified DNA fragments becomes around 67% (0.
We still do not know the mechanism underlying the improved fidelity of the unnatural base pairing using the [gamma]-amidotriphosphates.
