PCR amplification introduces errors into mononucleotide and dinucleotide repeat sequences.

The polymerase chain reaction (PCR) is used universally for accurate exponential amplification of DNA. We describe a high error rate at mononucleotide and dinucleotide repeat sequence motifs. Subcloning of PCR products allowed sequence analysis of individual DNA molecules from the product pool and revealed that: (1) monothymidine repeats longer than 11 bp are amplified with decreasing accuracy,...

Ligase-based detection of mononucleotide repeat sequences.

Up to 15% of all colorectal cancers are considered to be replication error positive (RER(+)) and contain mutations at hundreds of thousands of microsatellite repeat sequences. Recently, a number of intragenic mononucleotide repeat sequences have been demonstrated to be targets for inactivating genes in RER(+)colorectal tumors. In this study, thermostable DNA ligases were tested for the ability ...

Vectorette PCR isolation of microsatellite repeat sequences using anchored dinucleotide repeat primers.

We have developed a vectorette PCR approach to provide an improved method for isolation of microsatellite repeats. The modified procedure relies on PCR amplification using a vectorette-specific primer in combination with one of a panel of anchored dinucleotide repeat primers. The target DNA to be screened for microsatellite sequences can be from YAC, P1, cosmid, bacteriophage or plasmid clones....

Errors induced during PCR amplification

The Polymerase Chain Reaction (PCR) is one of the most widely used techniques in modern molecular biology to amplify a single or few copies of a piece of DNA sequences. The PCR products are used as inputs of many other applications such as diagnosis of diseases. Therefore the accuracy of the further analysis depends on the quality of the PCR outputs. In order to study the amplification process ...

The determination of the sequences present in the shadow bands of a dinucleotide repeat PCR.

A Polymerase Chain Reaction (PCR) of a DNA sequence containing a CA repeat produces a main band but also several shadow bands that differ by 2 base pairs below the main band. In the experiments described in this paper, these shadow bands were excised from a DNA sequencing gel and directly sequenced. It was found that the sequence in the CA repeat was ambiguous. However, the sequence 5' and 3' t...
