Select the correct statement for the figure given below.
Options
- AIt gives us a 3-dimensional view of a protein.
- BThe protein thread are folded into other forms like helix and pleated sheets is called the tertiary structure.
- CIn proteins, only right handed helices are observed.
- DAll portions of the protein thread are arranged in the form of a helix.
Correct answer
C. In proteins, only right handed helices are observed.
Step-by-step solution
Of course, only some portions of the protein thread are arranged in the form of a helix. In proteins, only right handed helices are observed. Other regions of the protein thread are folded into other forms in what is called the secondary structure (Fig. 9.3 b). In addition, the long protein chain is also folded upon itself like a hollow woollen ball, giving rise to the tertiary structure (Fig.9.3c). This gives us a 3-dimensional view of a protein.
