Question

Quizplus · Accepted Answer

The amino acid racemization method of dating is based upon the process whereby L-amino acids turn into D-amino acids over time. This process occurs after an organism dies and is no longer able to maintain its L-amino acid configuration. As the D-amino acids accumulate, the ratio of L-to-D amino acids changes and can be used to estimate the age of the organism or material being examined. This method is commonly used to date bones, shells, and teeth.
