between gene and protein was first articulated by Beadle & Tatum, who proposed the one-gene, one-enzyme hypothesis - which of the following statements contradicts this hypothesis? O 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.

Proteins

We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.  

Protein Expression

The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
