As part of the process of preparing scRNA-seq libraries, a diverse template is typically amplified by PCR. During amplification, spurious chimeric molecules can be formed between molecules originating in different cells. While several computational and experimental strategies have been suggested ...

Chimeric transcripts are commonly defined as transcripts linking two or more different genes in the genome, and can be explained by various biological mechanisms such as genomic rearrangement, read-through or trans-splicing, but also by technical or biological artefacts. Several studies ...

The human genome is far more complex than thought, with genes functioning in an unexpected fashion that scientists have wrongly assumed must indicate cancer, research from the School of Medicine indicates. Hui Li, PhD, of the Department of Pathology and ...

Scientists from the Spanish National Cancer Research Centre’s Structural Computational Biology Group, led by Alfonso Valencia, are making the largest ever catalogue of biological chimeras available to the public domain. Specifically, the new database comprises a c ollection of more ...

In ecological studies microbial diversity is nowadays mostly assessed via the detection of phylogenetic marker genes such as 16S ribosomal RNA. However, PCR amplification of these marker genes produces a significant amount of artificial sequences often referred to as chimeras. ...
