Ancient DNA from Human and Animal
Research on ancient DNA (aDNA) has the potential to enable molecular biologists and archeologists to decipher certain aspects of history by direct looking into the past. However, several major problems in this field limit the applicability of aDNA studies, most importantly contamination with modern DNA and postmortem DNA degradation. In this study we extracted and analyzed aDNA obtained from ~3...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولExtraction of DNA from Human Remains.
Improvements to analytical methods have made it possible for highly discriminative genotypic information to be gleaned from smaller and smaller amounts of sample material. This fact makes it practical to genotype samples or remains consisting of bone and tooth-samples that likely would not have yielded interpretable genotypic results a short time ago. In parallel, there have been improvements t...
متن کاملAuthenticated DNA from ancient wood remains.
BACKGROUND The reconstruction of biological processes and human activities during the last glacial cycle relies mainly on data from biological remains. Highly abundant tissues, such as wood, are candidates for a genetic analysis of past populations. While well-authenticated DNA has now been recovered from various fossil remains, the final 'proof' is still missing for wood, despite some promisin...
متن کاملAuthenticating DNA Extracted From Ancient Skeletal Remains
The survival of DNA, the most informative biological molecule, for periods of at least several thousand years in bone was demonstrated more than four years ago. However, difficulties with authenticating ancient DNA have made diagenetic studies problematic. It is therefore essential that these problems be overcome before the question of DNA survival can be addressed. Here we describe our work wi...
متن کاملStudy of Preservation Status and Dietary Reconstruction in Human Remains Recovered from Roopkund Lake through Chemical Analysis of Faunal Remains
The Present study carried out on the bone samples collected from Roopkund Lake in Chamoli Garhwal, Uttarakhand, which is located 5029 meters from main sea level in between Nanda Ghunghti and Trishuli peak. This historical site belongs to the 9th century A.D. All the samples selected for the study were dried in room temperature, as well as in hot air ovens at 32 degree Celsius. The Cleaning, pr...
