Similarity-Based Approach to Gene Prediction
Genes in different organisms are similar
The similarity-based approach uses known genes in one genome to predict (unknown) genes in another genome
Problem: Given a known gene and an unannotated genome sequence, find a set of substrings of the genomic sequence whose concatenation best fits the gene
