The major structural difference between soluble globular proteins and membrane proteins is: a. Hydrophobic residues are on the outside of the protein and polar residues are on the inside in membrane proteins b. There is no significant difference between soluble globular proteins and membrane proteins c. Hydrophobic residues are on the inside of the protein and polar residues are on the outside in membrane proteins d. Membrane proteins do not contain any secondary structure 2. Topoisomerases are enzymes that can: a. join two DNA fragments to become one. b. catalyze conformational change of a protein. c. cut DNA at specific site. d. catalyze the breaking and rejoining of DNA strands which produces DNA that is either more or less superhelical than the original.
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.
