This technique is versatile and offers a method of tracking cells in tissue with high spatial resolution. Biology Primer Extension Capture: Targeted Sequence Retrieval from Heavily Degraded DNA Sources Adrian W. Briggs1, Jeffrey M. Good1, Richard E. Green1, Johannes Krause1, Tomislav Maricic1, Udo Stenzel1, Svante Pääbo1 1Max-Planck Institute for Evolutionary Anthropology, Leipzig We present a method of targeted ancient DNA sequence retrieval, which we used to reconstruct the complete mitochondrial genomes of five Neandertal individuals. Comparison of these sequences with present day humans suggests that Neandertals had a long term low effective population size.
