"I took the scan down past the DNA level this time," she said.

This is accomplished at the DNA level using mutagenesis.

Someone will try to improve our species on the DNA level.

This grouping, while originally made on morphological grounds, now has considerable support at the DNA level.

"Primate evolution at the DNA level and a classification of hominoids".

At a DNA level many types of manipulations can be carried out.

Ingrid said, "We can confirm that at the DNA level.

No supergene has yet been characterized to the functional DNA level, but work is proceeding in a number of species.

The 1970s saw the first genetic engineering experiments, in which scientists learned to manipulate proteins, cells, and simple organisms at the DNA level.

We have to study this at the DNA level.
