Predicting New ORFs in Yeast Genome

A method for predicting first kind of open reading frame (ORF) is given,which is called Terminal Codon Method.The first kind of ORFs is the ORF that has not intron in it.The correctness of the method is examined by 6 260 known genes and ORFS of yeast genome and its successful rate is 99.9%.This result shows that the starting codon of yeast gene is always the ATG which is in close neighbor to the last terminal codon upstream.2 244 new ORFs with length not lower than 90a.a have been found.
