100 years after Sturtevant and the linear order of genes on chromosomes: an ECA cytogenetics session

Among the exciting Plenary Sessions at the European Cytogeneticists Association conference in Dublin – #ECA2013 – one marked 100 years since publication of Alfred H Sturtevant’s landmark research paper presenting the first genetic map of a chromosome (1913: J. Exp. Zool., 14 (1), … Continue reading

Repetitive DNA in the edible button mushroom

I have a mental picture of the structure of a typical plant genome and typical animal genome, with their  transposons (DNA and RNA), tandemly-repeated satellite sequences, minisatellites, microsatellites and other repeats. From this paper, I have a view of repeats in the second … Continue reading
