Paper Abstract
We have characterized function related DNA sequences of various organisms using informatics techniques,
including fractal dimension calculation, nucleotide and multi-nucleotide statistics, and sequence fluctuation
analysis. Our analysis shows trends which differentiate extremophile from non-extremophile organisms, which
could be reproduced in extraterrestrial life. Among the systems studied are radiation repair genes, genes involved
in thermal shocks, and genes involved in drug resistance. We also evaluate sequence level changes that have
occurred during short term evolution (several thousand generations) under extreme conditions.
