In samples of DNA isolated from two unidentified species of bacteria, X andY, adenine makes up 32% and 17%, respectively, of the total bases. Whatrelative proportions of adenine, guanine, thymine, and cytosine would youexpect to find in the two DNA samples? What assumptions have you made?One of these species was isolated from a hot spring (64 °C). Which species ismost likely the thermophilic bacterium, and why?
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.
