Sickle-cell anemia results in defective hemoglobin. Two enzymes are able to metabolize the same reaction. Alkaptonuria results when individuals lack a single enzyme involved in the catalysis of homogentisic acid. A mutation in a single gene can result in a defective protein. A single antibody gene can code for different related proteins, depending on the splicing that takes place post-transcriptionally.arrow_forwardWhat is the one-gene, one-enzyme hypothesis?arrow_forwardMention the industrial use of enzyme in molecular biology.arrow_forward
