There are six possible reading frames for any double-stranded DNA. In the following schematic drawing of a genomic region in Escherichia coli, stop codons in each of these frames are indicated by black bars. In which reading frame do you think the open reading frame (ORF) is translated in this region? Write down the frame number as your answer, e.g. 2.

An open reading frame is a stretch of DNA with no stop codons. Long open reading frames likely correspond to protein-coding genes in genomes that have uninterrupted genes.
