Bioinformatics is now an essential tool in many aspects of human molec
ular genetics research. Methods for the prediction of gene structure a
re essential components in genomic sequencing projects and provide the
key to deriving protein sequence and locating intron/exon junctions.
Sequence comparison and database searching are the pre-eminent approac
hes for predicting the likely biochemical function of new genes, altho
ugh sequence profiles derived from families of aligned sequences have
advantages in the detection of remote sequence relationships. The use
of sequence database analysis for large-scale comparative analysis of
genome sequence data from model organisms is emerging as the most impo
rtant recent development in the application of bioinformatics methods
for characterizing candidate disease genes.
