Bioinformatics
... is the study of the origin and descent of species, as well as their change over time. Recent developments in genome sequencing and the ubiquity of
fast computers enable researchers to trace evolution of species by tracing changes in their DNA. CEB research from the pre-genome era involved building ...
BLAST
... of BLAST programs, and the more practical CPU requirements explain why BLAST is vastly more used than the Smith-Waterman algorithm.
An extremely

fast as possible, which had the result that the opponent was deprived of all computational resources . However, programs in the Core War game did not ...
Ecological genetics
... studies wild populations of organisms.
Studies are often done on insects and other organisms that have short generation times, and thus evolve at
fast rates.
History
Although work on natural populations had been done previously, it is acknowledged that the field was founded by the Briton ...
Gradient

each point in the room, the gradient at that point will show the
direction in which it gets hottest. The magnitude of the gradient will
tell how
fast it gets hot in that direction.
Consider a hill whose height at a point ( x , y ) is
H ( x , y ) . The gradient of H at a point will
show ...
Immune system

Ion channel
