Sequencing analysis showed all cytosine bases not present in the CpG dinucleotide context were converted to thymine indicating complete bisulfite modification of the genomic template occurred.
Full-length extension of the primer on control and cross-linked template occurred, but both occurred very slowly.
(D ) Schematic model depicting how a one nucleotide 'backward-shift' relative to the template occurring during the transcription of the first three consecutive As might lead to the incorporation of four As at the beginning of the transcript.
Recent studies addressed the determination of the requirements for de novo centromere formation in S. pombe, in which centromere formation on naked DNA templates occurs efficiently only in the presence of heterochromatin (Folco et al, 2008).
We have shown that in M. grisea template switching occurs at specific sites within the initial template RNA which contains a characteristic consensus sequence.
Moreover, on particularly good substrates, such as the yeast IGS1 R ncRNA or the FOXL2 mRNA [4], template switching occurs in a large fraction of cDNAs produced.
In contrast, the prominent bands representing both types of trans-splicing at a single locus were not observed when AMV was substituted for Superscript II, although PCR products were still obtained, suggesting that some template switching occurs (Fig. 4B).
In the process of viral DNA synthesis, template switching occurs by translocation of RT between two genomic RNAs, and results in both intra-molecular and inter-molecular recombination.
