What is the difference between one-gene/one-protein hypothesis and one-gene/one-polypeptide hypothesis?
What is the difference between one-gene/one-protein hypothesis and one-gene/one-polypeptide hypothesis?
Homework Answers
One gene-one Protein hypothesis was first given by Archibald Garrod in 1909. It said that each gene codes a single, specific enzyme. Thus under this hypothesis, each gene is responsible for the enzyme initiating a single step in a metabolic process.
One gene-one Polypeptide hypothesis was first given by George Beadle in 1945. It said that each gene is responsible for the synthesis of a single polypeptide. This theory was modified because it was realized that genes also encoded nonenzyme proteins and individual polypeptide chains.

What is the difference between a polypeptide and a protein? I'm not understanding this sentence in my textbook: "While the terms polypeptide and protein are sometimes used interchangeably, a polypeptide is technically a polymer of amino acids, whereas the term protein is used for a polypeptide or polypeptides that have combined together, often have bound non-peptide prosthetic groups, have a distinct shape, and have a unique function."

Which of the following is a difference between the use of a reporter gene to study gene regulation (ex. promoter deletion mapping with a reporter protein) and using a reporter gene to study protein localization? Select all that apply? o When studying protein localization, a fusion protein is created which consists of both the protein of interest and the reporter protein.

Imagine a transmembrane protein consisting of a single polypeptide chain. The protein has alpha helices that pass through the membrane seven times. Between each segment that passes through the membrane are loops that extend into the cytoplasm or into the extracellular fluid. The C-terminus of the protein extends into the cytoplasm and the N-terminus extends into the extracellular fluid. What is the minimum number of polar stretches* in the primary structure of this protein? *polar stretches are contiguous regions of...
