First, he noted that the nucleotide composition of DNA varies among species. In other words, the same nucleotides do not repeat in the same order, as proposed by Levene. Second, Chargaff concluded ...

In 1920, however, a farmer in the African nation of Namibia, then part of British-controlled South Africa, made an ...

Our analysis of fold characterisation (see Methods) identified 73 such regions (Table S3) with at least 25 nucleotides in length ... This approach can be extended to other RNA viruses and potentially ...
