FeNi or NiFe is an acronym used to refer a family of iron alloys.
<h3>What is alloy?</h3>
An alloy is a mixture of chemical elements that contains at least one is a metal.
<h3>Alloy of iron</h3>
The alloy of iron-nickel can be abbreviated as FeNi, which implies iron-nickel.
where;
- Fe stands for iron
- Ni stands for Nickel
Thus, FeNi or NiFe is an acronym used to refer a family of iron alloys.

Before the development of electrophoresis to separate macromolecules, high-speed centrifugation was used to isolate DNA.
A laboratory procedure called electrophoresis is used to divide DNA, RNA, or protein molecules according to their size and electrical charge. The molecules are moved by an electric current through a gel or other matrix. The technology of electrophoresis is crucial for the separation and examination of nucleic acids. At the lab bench, cloned DNA fragments are frequently isolated and worked with using nucleic acid electrophoresis.
High-speed centrifugation employs centrifugal force to separate particles with various densities or masses suspended in a liquid. High-speed rotation of the solution inside the tube causes each particle's angular momentum to experience centrifugal forces inversely proportionate to its mass.
