Scientists analyzing the genomes of thousands of people across Japan discovered evidence for a previously overlooked third ancestral group, challenging the long-accepted “dual origins” theory. The ...

For years, scientists believed the origins of the Japanese population could be traced back mainly to two ancient groups. But a major new DNA study is now challenging that long-held belief and ...

Figure 1: RNA-seq data uses short reads of mRNA which is free of intronic non-coding DNA. These reads must then be aligned back to the reference genome. Credit: Technology Networks. Early RNA-seq ...

SLE is a complex autoimmune disease that results from the interplay of genetics, epigenetics and environmental exposures. DNA methylation is an epigenetic mechanism that regulates gene expression and ...

Hybridization between complementary strands of DNA enables the interrogation of unknown DNA by comparison with DNA of known sequence or genomic context. DNA microarrays containing hundreds of ...

Microarrays are a two-dimensional arrangement of biological samples, with samples placed in spots numbering in the thousands and organized into columns and rows. They allow for efficient analysis of ...

Two weeks ago, Sen. Elizabeth Warren released the results of a genetic test showing she has a small but detectable amount of Native American DNA. The report concluded there is “strong evidence” she ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
