We can estimate this time by comparing molecular sequences in the two species.

Recent times have brought about the possibility to get molecular sequences from single cysts or single cells.

To help classify a virus, scientists need to know its basic structure, or molecular sequence.

Databases and software tools for analyzing data from molecular sequences to protein structures to complete genomes.

With this technology researchers have been able to study the molecular sequences associated with many human diseases.

Emile had two so he could test various molecular sequences for efficiency, speed, and capacity at the same time.

For molecular sequences, this problem is exacerbated when the taxa under study have diverged substantially.

Smallpox will be one of the few viruses whose molecular sequence is known.

Treefinder is a free computer program for the likelihood-based reconstruction of phylogenetic trees from molecular sequences.

They appear to be related to the waxwings, and at least one study based on molecular sequences suggests that it belongs to the same group.
