These cause of this slippage is due to the low processivity of the DNA polymerases combined with. Multiple mechanisms have been proposed to explain the origin of indel mutations including DNA strand slippage 5 misinsertionmisalignment 6 meltingmisalignment 7 and dNTP-stabilized misalignment. Thermococcus litoralis DNA polymerase Vent is also able to slip. We show that slippage involves DNA polymerase pausing which must take place within the direct repeat and that the pausing polymerase dissociates from the DNA.
Moreover DNA polymerases that have a constitutive strand-displacement activity such as Bacillus stearothermophilus DNA polymerase Bst do not slip.
89 All of these mechanisms include a base unstacking process that changes the probability of the right templateprimer base pair at the polymerase active site. Both slipped-strand structures should be recognized by the DNA mismatch repair pathway d k and the error corrected e 1 resulting in no net length change f m. The most commonly proposed mechanism for indel generation is slipped strand mispairing also known as replication or polymerase slippage 34. Cause of DNA Sequence Slippage Problems. The sequencing DNA polymerase skips over one or more bases make a product that is one or more bases shorter or longer. These cause of this slippage is due to the low processivity of the DNA polymerases combined with.

We also present evidence that upon polymerase dissociation only the terminal portion of the newly synthesized strand separates from the template and anneals to another direct repeat. Slippage might occur either in the active site of the enzyme or before the substrate binds to the enzyme 9. Ad Taq Polymerase At 003 Per Unit. We show that slippage involves DNA polymerase pausing which must take place within the direct repeat and that the pausing polymerase dissociates from the DNA. DNA polymerase III falls off of the DNA template at the repeat region then reattaches at a more distant site.

Ad Unlimited access to DNA market reports on 180 countries. Cause of DNA Sequence Slippage Problems. Polymerase slippage can cause the newly created DNA strand to contain an expanded section of DNA. During replication b polymerase slippage may occur leading to a loop out on the either the daughter strand c or the template strand j. To analyse DNA polymerase dissociation during slippage primer extensions were performed using labelled primed ssDNA a limiting amount of DNA polymerase and heparin as a trapping agent.

During replication the DNA polymerase and newly synthesized DNA strand complex sometimes temporarily dissociates from the template DNA. Polymerase slippage can cause the newly created DNA strand to contain an expanded section of DNA. By slippage we mean the extension of a primertemplate complex containing a loop in either the primer or template strand by a DNA polymerase. Thermococcus litoralis DNA polymerase Vent is also able to slip.
