DNA bases damaged by alkylation are removed by distinct strategies.

It is dependent on the sequence of the DNA bases.

But, obviously, light emissions on their own don't actually say anything about a DNA base.

It now seems that it will be impossible to complete the human genome in terms of sequencing every DNA base.

A DNA base can mutate more than once, however.

The resulting variations in the way that DNA bases are presented to proteins can thus affect the recognition mechanism.

Instead, if a given DNA base is identical in all the mitochondria within a cell, it's said to be "homoplasmic."

More recently he has been inventing and applying new chemical methods to study epigenetic changes to DNA bases.

Smallpox virus, for instance, has a genome of only 186,000 DNA bases.

However, there were no interactions seen between the metal and the DNA bases.
