What following statement is TRUE concerning motifs and domains? a) Both motifs and domains are independently stable. b) Domains undergo dynamic individual changes that affect the entire protein c) B-a-ß loops, B barrels, and helix-turn-helix structure are types of domains d) Motifs and domains are part of secondary structural elements e) Ab initio computations predict motif folds accurately a majority of the time
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.
What following statement is TRUE concerning motifs and domains?
a) Both motifs and domains are independently stable.
b) Domains undergo dynamic individual changes that affect the entire protein
c) B-a-ß loops, B barrels, and helix-turn-helix structure are types of domains
d) Motifs and domains are part of secondary structural elements
e) Ab initio computations predict motif folds accurately a majority of the time
My guess is B.
The proteins are folded into their three dimensional structure in order to gain biological function.
A motif is a certain grouping of the super secondary elements of proteins such as alpha helices and beta structures.
A domain represents a functional unit of a protein.
