Which of the following statements about electron microscopy are true? a) Most existing protein structures have been resolved using electron microscopy b) Electron microscopy is not used in structural biology as it can not give as high a resolution as X-ray crystallography and NMR c) The smaller a protein, the easier it is to solve its structure with electron microscopy d) By taking pictures of the same protein frozen in ice thousands of times and then adding them together, you get a high-resolution image of the protein e) The first protein structure with true atomic resolution was solved using electron microscopy last year
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.
