Genetics: Analysis and Principles 5th Edition by Robert Brooker

Exercise 46

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.
