求翻译：We extracted the DNA contained in samples of bones and teeth from 10 skeletons excavated from the Gravette site (400–1000 AD, south of France). Ancient DNA was analysed by autosomal short tandem repeats (STRs). The DNA present in these ancient remains appeared very degraded, but nevertheless, better conserved in tooth 是什么意思？ 待解决

我们从10骷髅从gravette网站（400-1000广告，法国南部）出土骨骼和牙齿样本中提取了DNA。古DNA分析常染色体短串联重复序列（STR基因座）。在这些古老的遗骸的DNA目前出现退化，但尽管如此，更好地在牙骨标本比保守。此外，我们发现，从古老的牙髓中提取的DNA是不豁免聚合酶链反应（PCR）抑制剂，它可能会导致极端的DNA片段。补充步骤的净化与适应协议消除这种抑制作用。

我们抽取的样本中dna骨骼和牙齿化石出土于10的gravette站点(400-1000ad,法国南部)。 古dna是由显性遗传分析短串联重复(可疑交易报告)。 目前的dna在这些古代的遗迹似乎非常退化,但无论如何,更好地保存在齿比骨骼样本。
