In principle, the specificity of the reaction depends on the inability of non-proofreading DNA polymerases (e.g. Taq) to extend 3' terminally mismatched oligonucleotides but not on the length of the primers, which makes primer design straightforward by avoiding complex design considerations [32].
We can similarly modify the irreducible overlap detection algorithm by allowing the right-extension phase to extend to mismatch bases or gaps.
Each PM probe is 25 bp long and the complete match score to target sequence is 25, and gap open, gap extend and mismatch penalty are 5, 2 and 3, respectively as previously used in Horiuchi et al. [ 19].
To exclude the possibility that the lack of luciferase rescue was because of incomplete destruction of target sites, we extended the mismatch from 2 to 7 nt (complete seed mismatch) on selected target sites (mir-17/-20a/-106b and mir-34a/-34c/-449 – Supplementary Figure 1).
Pol ζ is unique in that it can extend terminal mismatches, whereas more processive polymerases cannot.
So when a lesion is encountered, the replication fork will stall, PCNA will switch from a processive polymerase to a TLS polymerase such as Pol ι to fix the lesion, then PCNA may switch to Pol ζ to extend the mismatch, and last PCNA will switch to the processive polymerase to continue replication.
Each SNP and a minimum of five adjacent SNPs were considered sequentially, with length of shared haplotypes extended until mismatch.
These two consecutive pause sites were also observed with the control substrate but to a lesser extent, as hPolι is known to preferentially misincorporate dG opposite template dT and inefficiently extend the mismatch.
There can be more than one such maximal match, and all these matches are extended to k-mismatch common substrings.
For Dpo4, the S-cdG T miS-cdG Td pair was extended 10-fold mismatchedy relative to the S-cdG:C pair, wasch itsextendednded quite inefficiently (i.e., >10-fold less efficiently than a G:C pair) (Table 8).
