WebApr 21, 2024 · However, chimeric reads, generated in MDA, cause severe disruption in many single-ce … As the most widely-used single cell whole genome amplification (WGA) approach, multiple displacement amplification (MDA) has a superior performance, due to the high-fidelity and processivity of phi29 DNA polymerase. WebChimeras are sequences formed from two or more biological sequences joined together. Amplicons with chimeric sequences can form during PCR. Chimeras are rare with shotgun sequencing, but are common in amplicon sequencing when closely related sequences are amplified. Although chimeras can be formed by a number of mechanisms, the majority of ...
