Question

In bacteria, the majority of genes have a start codon ATG (orAUG in mRNA; because prediction is done at the DNA level, T is used in place of U), which codes for methionine.

(a) True

(b) False

The question was asked in an interview for job.

This key question is from Gene Prediction in Prokaryotes topic in chapter Gene and Promoter Prediction of Bioinformatics

Answer 1

The correct answer is (a) True

To explain I would say: Occasionally, GTG and TTG are used as alternative start codons. But methionine is still the actual amino acid inserted at the first position.
