bivalent etymology

Etymology

The word "bivalent" is derived from two Latin roots:

• bi-: meaning "two"
• valens: meaning "strong" or "powerful"

Meaning

In its most general sense, "bivalent" refers to something that has two equal or comparable values, strengths, or powers. It can also specifically refer to:

In Chemistry:

• A molecule that has two bonding sites
• An ion with a valence of two

In Biology:

• A chromosome with two identical chromatids
• A nucleosome containing two histone proteins

Origin

The term "bivalent" was first used in the scientific literature in the late 19th century by the German cytologist Theodor Boveri. He used the term to describe the paired chromosomes that are observed during cell division.

Examples

• Water is a bivalent molecule because it has two hydrogen atoms and one oxygen atom, which share two pairs of electrons.
• The calcium ion (Ca2+) is a bivalent ion because it has a charge of +2.
• During meiosis, homologous chromosomes pair up to form bivalents.
• Each nucleosome in a chromatin fiber is composed of a bivalent histone octamer.
