The helical twist angle between base pairs averages 34.1 overall, giving a helix order of 10.6, corresponding closely to that of random sequence DNA in solution.

What has brought Italian geneticists into the discussion are new abilities to sequence DNA and trace people's origins.

The ability to sequence DNA quickly and cheaply will also provide the technological basis for a new era in drug development.

Mr. Hunkapiller's unit is a principal manufacturer of the machines used to sequence DNA, or determine the order of chemical units.

Machines have been developed, and repeatedly improved, to sequence DNA and proteins automatically.

This preservation allowed researchers to sequence DNA from the brains.

In order to perform the test on a DNA sequence or gene, you need to sequence homologous DNA for at least 3 individuals.

Attempts to sequence DNA from the one known sample failed.

The field of early evolution has become extremely active, spurred by new computational tools and the torrent of data from machines that sequence DNA.

New technology now allows scientists to directly sequence DNA which has identified even more genetic variation than was previously detected by protein electrophoresis.
