(a) True

(b) False

The question was asked by my school principal while I was bunking the class.

My question is taken from Gene Prediction in Eukaryotes in section Gene and Promoter Prediction of Bioinformatics

Answer 1

The correct option is (a) True

The explanation is: The program scans the query sequence with windows of variable lengths and scores for coding potentials and finally produces an output that is the result of exon candidates. The program is currently trained for human, mouse, Arabidopsis, Drosophila, and Escherichia coli sequences.
