Cloning of ribosomal its pcr products creates frequent, non-random chimeric sequences – a test involving heterozygotes between gymnopus dichrous taxa i and ii... Chimeras and PCR-induced mutations are common in cloned PCR products and may result in incorrect sequence information in public databases
On the problem of masking special errors by signature analyzers... Due to the linearity of any LFSR, this happens if and only if the 'error sequence' which is obtained by the 'exor' operation from the correct and the incorrect sequence, leads to the zero signature....
The 3' terminal oligonucleotide of e. coli 16s ribosomal rna: the sequence in both wild-type and rnase iii- cells is complementary to the polypurine tracts common to mrna initiator regions.... Data presented here explains the previous derivation of an incorrect sequence (AUCCUCACUUCAOH) by others....
An example of missannotation and missalignment with the rhemac2/ncbi annotation.... The potentially incorrect sequence regions are shown in yellow background....
