Researchers have mapped the spatial distribution of around 700 long non-coding RNAs, otherwise known as lncRNAs, in the testes. The team discovered much higher levels of lncRNAs in the testes than had ...
De novo gene evolution describes the process by which entirely new genes originate from previously non-coding DNA rather than from the duplication and divergence of existing genetic material. This ...
Non-coding DNA variants contribute to acute lymphoblastic leukemia (ALL) chemotherapy resistance. St. Jude Children's Research Hospital scientists have identified specific DNA variants in the ...
