Question

In the ab initio–based approaches—they rely on two major features associated with genes: one of them being the existence of gene signals, which include start and stop codons, intron splice signals, transcription factor binding sites, etc.

(a) True

(b) False

This question was posed to me in examination.

The doubt is from Categories of Gene Prediction Programs in chapter Gene and Promoter Prediction of Bioinformatics

Answer 1

Right option is (a) True

Explanation: They also include ribosomal binding sites, and polyadenylation (poly-A) sites. In addition, the triplet codon structure limits the coding frame length to multiples of three, which can be used as a condition for gene prediction.
