Question

Which mode of representation of the tertiary structure of a protein provides the most information about the location and orientation of secondary structural elements?

1) Ramachandran plot
2) Ribbon diagram
3) Space-filling model
4) Ball-and-stick model

Answer 1

The Ribbon diagram is the mode of representation of the tertiary structure of a protein that provides the most information about the location and orientation of secondary structural elements.

Step-by-step explanation:

The mode of representation of the tertiary structure of a protein that provides the most information about the location and orientation of secondary structural elements is the Ribbon diagram. The Ribbon diagram uses a smooth ribbon-like representation to visualize the protein's secondary structure, such as α-helices and β-sheets.

This representation allows for a clear understanding of the overall folding pattern and arrangement of these secondary structural elements in the protein. It provides a more intuitive visualization compared to other modes of representation, such as the Ramachandran plot, which focuses primarily on backbone torsion angles, or the space-filling and ball-and-stick models, which emphasize atoms and bonds.
