Proteins levels of protein structure levels of protein structure and a double-stranded dna molecule the catabolite activator protein. Protein art and what proteins really look like individual proteins are so small that you can’t actually see them, not even with most microscopes so when you see a “picture” of a protein, you are really looking at a drawing or computer model of the protein’s structure. The overall three-dimensional shape of an entire protein molecule is the tertiary structure the protein molecule will bend and twist in such protein structure.

In the nucleus of each cell, the dna molecule is packaged into thread-like structures called chromosomes each chromosome is made up of dna tightly coiled many times around proteins called histones that support its structure chromosomes are not visible in the cell’s nucleus—not even under a. Levels of protein structure there this is the shape (spatial organization) of an entire protein molecule protein folding is largely self-organising. Disulfide bonds are important in protein structure because they allow the linkage of two different parts of a protein molecule to—and thus the formation of loops in.
