Abstract

High-throughput direct sequencing techniques have recently opened the possibility to sequence genomes from Pleistocene organisms. Here we analyze DNA sequences determined from a Neandertal, a mammoth, and a cave bear. We show that purines are overrepresented at positions adjacent to the breaks in the ancient DNA, suggesting that depurination has contributed to its degradation. We furthermore show that substitutions resulting from miscoding cytosine residues are vastly overrepresented in the DNA sequences and drastically clustered in the ends of the molecules, whereas other substitutions are rare. We present a model where the observed substitution patterns are used to estimate the rate of deamination of cytosine residues in single- and double-stranded portions of the DNA, the length of single-stranded ends, and the frequency of nicks. The results suggest that reliable genome sequences can be obtained from Pleistocene organisms.

  • The authenticity of the human reads obtained from archaeological dental calculus and dentine was assessed by examining damage patterns typical of ancient DNA.

    “The authenticity of the human reads obtained from archaeological dental calculus and dentine was assessed by examining damage patterns typical of ancient DNA (Briggs et al., 2007; Ginolhac et al., 2011; Jonsson et al., 2013).”

    The Abstract and Results and Discussion describe characteristic ancient-DNA damage patterns, supporting their use as patterns to examine in the citing study. But Results and Discussion cautions that contaminating modern human DNA can show typical misincorporations, so damage patterns alone cannot reliably establish the authenticity of human reads.

  • aDNA damage results in C-to-T and G-to-A substitutions.

    “This therefore results in a pattern of C-to-T substitutions. When a double-stranded library preparation is used, these substitutions can occur on the opposite strand thus resulting in G-to-A substitutions due to base complementarity.”
  • An excess of C-to-T substitutions arise near read termini due to the accumulation of post-mortem cytosine deamination.

    “An excess of these substitutions arise near read termini due to the accumulation of post-mortem cytosine deamination (Briggs et al. 2007).”

  • All samples showed nucleotide misincorporation patterns characteristic of ancient DNA.

    “MapDamage 2.0 (ref. 60) has been used to evaluate fragment lengths and nucleotide misincorporation patterns of the provided samples, all of which showed levels that are characteristic for ancient DNA13.”
  • Authentic ancient DNA exhibits characteristic damage including short DNA fragment lengths, a high rate of cytosine deamination at the termini of DNA fragments, and an enrichment of purine bases at DNA breakage sites.

    “Briefly, authentic ancient DNA is known to exhibit characteristic damage that includes short DNA fragment lengths, a high rate of cytosine deamination at the termini of DNA fragments, and an enrichment of purine bases at DNA breakage sites.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
