Which of the following describes the overall three-dimensional folding of a polypeptide?

A) Primary structure

B) Secondary structure

C) Tertiary structure

D) Quaternary structure

E) None of the above

Answer: C. Tertiary structure.

Explanation: The overall three-dimensional folded structure of a polypeptide is referred to as the tertiary structure. The structure is due to the relationship between the R-groups of the amino acids that constitute the building blocks of proteins.

The sequence initiated by amino acids that proteins tread is what gives the three dimensional shape to the tertiary state of a polypeptide.

The bond is a major contributing factor for the three dimensional shape of the tertiary structure. This formidable bond is known as the disulfide bond, which is a special kind of chemical covalent bonding.

How does 3D printing work?

There are three different ways 3D printers work but they all rely on the printer converting a design into individual 2D slices which are then combined to make the final 3D object. The first method uses a pool of chemicals that turns solid when light, typically a UV laser, is shone on to it. The […]

Cigarette smoking causes emphysema.

Nearly everyone knows that smoking causes lung cancer, but did you know that smoking causes a number of other serious lung diseases?
