81. You have used the primary amino acid sequence of a newly identified protein (of unknown function) to make a hydropathy plot. From this plot you believe it might be a transmembrane receptor. This is because the plot tells you a. the secondary structure is likely made up of several B sheets. b. the secondary structure is likely made up of a-helices. c. the protein would be readily hydrolyzed if in an aqueous environment. d. on average, there are a lot of hydrophobic amino acids in the protein. there are several hydrophobic areas interspersed with short hydrophilic stretches. that е. 82. You are studying a mutant type of garter snake known for its odd slithering movement. You isolated the mutated gene and this morning you just got the results from your DNA sequencing. What would be your first step towards determining the potential function of the protein encoded by this gene? a. Use X-ray crystallography to determine the tertiary structure of the protein. b. Use computer programs that predict the secondary and tertiary protein structure. c. Search gene/protein databases to find proteins of known function that have sequence homologies. d. Make antibodies to the protein and use these to determine where the protein is localized in the snake tissues.

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.
