thermochemistry
Thermochemistry refers to chemical thermodynamics – the energetic principles that underlie chemical reactions, phase changes, and solution formation. In essence, thermodynamically favourable reactions move readily from reactants to products, and are accelerated in the presence of specific catalysts or enzymes.

Horizontal Genomics: Mobile genetic elements: the agents of open source evolution.
Mobile genetic elements: the agents of open source evolution.: "Horizontal genomics is a new field in prokaryotic biology that is focused on the analysis of DNA sequences in prokaryotic chromosomes that seem to have originated from other prokaryotes or eukaryotes. However, it is equally important to understand the agents that effect DNA movement: plasmids, bacteriophages and transposons. Although these agents occur in all prokaryotes, comprehensive genomics of the prokaryotic mobile gene pool or 'mobilome' lags behind other genomics initiatives owing to challenges that are distinct from cellular chromosomal analysis. Recent work shows promise of improved mobile genetic element (MGE) genomics and consequent opportunities to take advantage - and avoid the dangers - of these 'natural genetic engineers'."
