Taq Polymerase Mismatches

MutS, Mutation In DNA: Application
DNA(250 ng) was amplified with Taq polymerase to generate fragments 100 bp long; 27 cycles were performed. and some mismatches (e.g., A/C) are, in fact, bound only poorly (7). Eachpair ofalleles produces twodifferent mis- … Get Content Here

Polymerase Chain Reaction (PCR)
Note: different buffer receipes follow at the end of this protocol – MgCl 2 (25mM is convenient) – Taq polymerase – dNTPs (2mM stock) Note: a 2mM mismatches or partial annealing may be tolerated: this is fine if one wishes to amplify … Retrieve Document

Structural model of modified primer bound to Taq polymerase. The bulky moiety points into the major groove of the DNA, away from the active site of the short probes to be utilized, which cover less sequence space of the intended target, and are therefore less likely to impinge on multiple mismatches … Read More

Mismatch Discrimination Using PCR
3’ and internal mismatches between primer-template duplexes are tolerated under appropriate conditions. The discrimination of different PCR targets is based on the fact that taq DNA polymerase lacks 3’(5’ exonuclease activity and that mismatched 3’ termini are extended at a lower rate than … Retrieve Here

Taq polymerase has a half-life of 30 min at 95oC, one should not do more than about 30 amplification cycles: however, it is possible to reduce the annealing If a Ta is too low : one or both primers will anneal to sequences other than the true target, as internal single-base mismatches or … Retrieve Full Source

Promoter (genetics) – Wikipedia, The Free Encyclopedia
For the transcription to take place, the enzyme that synthesizes RNA, known as RNA polymerase, must attach to the DNA near a gene. promoters with complete conservation of the -10/-35 hexamers has been found to transcribe at lower frequencies than those with a few mismatches with … Read Article
