The other was to identify bacteria by examining DNA.

Contradicting the results discovered while examining mitochondrial DNA, they demonstrated a range of genetic contribution to non-African modern humans ranging from 1% to 4%.

By examining DNA, we can plot the bumpy ride to humanity's astonishingly populous position, says Steve Jones.

Upon examining DNA from the moa, they believe that the kiwi is more closely related to its Australian cousins.

That is because his test examines only mitochondrial DNA, which is inherited through the mother.

Examining DNA, biologists can identify individual animals and their lineage, measure their age and determine whether they are breeding.

Sequana and the cancer institute examined DNA from members of families with hereditary melanoma.

When they examined DNA from the wild Spix macaw and found this marker absent, the researchers said concluded that the bird was a male.

A study examining mitochondrial DNA from skin biopsies taken from 13 sampling locations, considered genetic diversity and structure among hippo populations across the continent.

By examining DNA, oncologists can determine if patients are high risk or low risk of the cancer returning quickly following treatment.
