It has been shown that, in gapped substrates, PolDom has the ability to dislocate and realign the template, extending the primer by inserting nucleotides complementary to templating bases distal to the primer terminus (Yakovleva and Shuman, 2006; Pitcher et al., 2007b).
During DNA extension, telomerase uses a short segment within its integral RNA subunit as the template to extend the 3′ end of the G-rich strand of the telomere (Greider and Blackburn 1989).
The leftover contigs were checked by BlastN versus the template, and two contigs that were not covered by any part of the template were extended by several rounds of assembly versus the 454 reads until they were closed.
We filled gaps in the Pcdh constant region in scaffold_480 and scaffold_160 by PCR using fugu genomic DNA as a template and extended the sequences by identifying and sequencing overlapping cosmid or BAC clones (see Methods).
In summary, footprinting data on the ternary complexes are consistent with close contact between RT and the first two or three nucleotides of the template extending beyond the primer terminus.
Comparatively, the template methods via the polymerization on the surfaces of the templates could extend the polymers or monomers used [15 17] and morphologies of the capsules [18, 19].
The template strand extends over the bridge helix into the active centre generally along the path it takes in the EC.
In a second round of PCR the DNA template was extended with these regulatory DNA sequences supplied in the RTS Wheat Germ Linear Template Generation Set, His6-tag (Roche Applied Science).
Once base paired, the reverse transcriptase would switch the template and extend into the linker sequences allowing PCR amplification of full-length cDNA using a single primer (the 5'-linker has the same sequences as the linker containing poly T used for the synthesis of the first strand cDNA).
The PCR inhibition by a dye, as characterized by a delay in Ct, is most likely due to the dye's interference with the chain extension step, where the dye may bind to the single-stranded template, thereby serving as "road bumps" to the extending primer-template complex.
