A scientist has obtained a sequence of chimpanzee (pan troglodytes) dna, which is believed to encode a chemokine receptor gene. the scientist is examining the sequence to identify potential open reading frames (orfs), which contain both a start and stop codon. using the partial sequence of chimpanzee dna below, identify the total number of orfs.

Explanation:

Start and stop are delimited by  

From the following section of DNA of chimpanzee (pan troglodytes)

From a coding         5' 3'

matching template  3' 5'

therefore the transcript mRNA will be

5' 3'

Therefore there is only one ORF in the sequence above.
