Analysis of DNA From Permafrost Specimens

这项研究提出了利用新的分子方法来恢复，扩增和序列的DNA从致密的沉积物的永久冻土仍然在阿拉斯加和育空地区，代表独特的样本的动物群的居民在过去的40,000年。 PI提出了一种小型，创新和实验性的方法，该方法很有可能获得可以解决极地生物学长期存在的问题的数据，包括人口流动，迁移和生物适应。 基础研究技术包括使用古代DNA技术提取和表征永久冻土稳定标本中保存的DNA。

This study proposes to utilize new molecular approaches to recover, amplify, and sequence DNA from dense deposits of permafrost remains in Alaska and the Yukon which represent unique samples of the faunal inhabitants of the area over the past 40,000 years. The PIs propose a small, innovate and experimental approach which has a high possibility of obtaining data that can address long standing questions in polar biology including population movements, extinctions, and biotic adaptations. The basic research techniques involve using ancient DNA techniques to extract and characterize preserved DNA in permafrost stabilized specimens.
