Where are the genes?
The objective of gene finding is to identify the regions of
DNA that are genes. Ideally, we want to make statements
like: “Positions 28,354 through 29,536 of this genome code
a protein.” Once we have identified a gene, it is easy to
translate the DNA code into the sequence of amino acids
that make up the corresponding protein.
The mathematical challenge here is to identify patterns in
DNA that reliably indicate where a gene starts and ends,
especially in eukaryotes.
