Question:

Give brief definitions or unique descriptions of the following terms:

A) neutral drift

B) sickle cell trait

C) secondary structure

D) torsion angle

E) domain

F) quaternary structure

Definitions:

Different terms and different definitions are used in chemistry according to the situation. All the terms mentioned in the question are different from each other.

Answer and Explanation: 1

A) Neutral drift: The integration of mutations that do not affect the protein in its current environment. The adaptive changes in events occur fast due to neutral drift.

B) Sickle Cell trait: Sickle cell trait is the phenomenon of passing the genetic mutation of sickle cell from one generation to the next i.e. from parents to the children.

C) Secondary structure: Secondary structure of the protein is the regular repetitive folding of the polypeptide chains in two dimensions.

D) Torsion angle: Torsion angle is the angle between the two bonds that are formed between various atoms in Newmann projection.

E) Domain: In solid-state, the arrangement of the atoms in clusters that are aligned in the same direction in ferromagnetic substances.

F) Quaternary structure: Incorporation of several polypeptide chains to give a closely packed rearrangement.
