Fragments of DNA have been extracted from the remnants of extinct woolly mammoths, amplified, and sequenced. How can these fragments of DNA now be used?
A) to introduce certain mammoth traits into relatives, such as elephants
B) to clone live woolly mammoths
C) to understand the reasons why mammoths went extinct
D) to better understand the evolutionary relationships among members of related taxa

Question

Quizplus · Accepted Answer

Fragments of DNA extracted from extinct species can be used to better understand the evolutionary relationships among members of related taxa. This allows researchers to study species that are no longer alive and gain insight into their genetic history and relationships with other species. This information can help inform conservation efforts and shed light on the factors that led to extinction. However, it is currently not possible to clone live woolly mammoths, and introducing mammoth traits into living relatives such as elephants would require significant genetic engineering and ethical considerations.
