In this chapter, we considered a computer program that can translate a DNA sequence into a polypeptide sequence. A researcher has a sequence file that contains the amino acid sequence of a polypeptide and runs a program that is opposite to this program. This other program is called BACKTRANSLATE. It takes an amino acid sequence file and determines the sequence of DNA that would encode such a polypeptide. How does this program work? In other words, what genetic principles underlie this program? What type of sequence file would this program generate: a nucleotide sequence or an amino acid sequence? Would the BACKTRANSLATE program produce only a single sequence file? Explain why or why not.
