Question

The best style to examine amino acid side chains of the protein is:

A) Space-filling model
B) Ribbon diagram
C) Wireframe model
D) Ball-and-stick model

Answer 1

The Ball-and-stick model is the best style to examine amino acid side chains of a protein, as it clearly shows the atoms, bonds, and spatial arrangement of the side chains.

Step-by-step explanation:

The best style to examine amino acid side chains of a protein is the Ball-and-stick model. This model uses "balls" to represent atoms and "sticks" to signify the bonds between them, making it easier to observe the spatial arrangement and properties of the side chains. For instance, in the alpha-helix and beta-pleated sheet structures of proteins, the ball-and-stick models clearly show the intrachain hydrogen bonding and how the side chains extend from the protein backbone.
