Meaning of Nucleus

What is the Core:

A core is central or most important part of something. The word, as such, comes from the Latin nucleus, which means ‘edible part of the nut’ or ‘fruit stone’. It is the diminutive of the Latin voice nux, nuciswhich we can translate as ‘nut’

Thus, a nucleus becomes the marrow of a thing, that which is primordialwhich cannot be dispensed with.

For example, in a group of people, the core would be the group of individuals whose weight or hierarchy determines the direction or decisions of this organization: “The hard core of the team is against the departure of the technician.”

Likewise, a nucleus can be the stone of a fruit, a group of houses, the central part of an atom, a star or a cell, among other things.

Synonyms of core, in this sense, are center, axis; heart, medulla, entrails, core or crux.

Cell nucleus

In biology, the cell nucleus would be the command of cellular activities, since it contains the genetic material (DNA) for the development and functioning of the cell.

The cell nucleus is located in the center of eukaryotic cells, surrounded by a nuclear membrane. It is in charge of maintaining the genetic integrity of the cell and controlling cellular activities.

Likewise, inside the cell nucleus is the nucleolus, a corpuscle made up of proteins and ribonucleic acid that is involved in protein synthesis.

core of the earth

The terrestrial core is the central part of the interior of the globe. It has an approximate radius of 3,500 kilometers. It is formed, fundamentally, by iron, nickel and other elements with less presence such as sulfur and oxygen. It consists of a solid inner core and a liquid outer core. It represents 60% of the total mass of the Earth.

syntactic core

In grammar, we speak of a head usually in reference to the head of a phrase. The phrase is a word or a group of words organized around a nucleus. The syntactic nucleus is the element with the highest hierarchy within a phrase, since it is in charge of determining the way in which the other elements will be ordered around the phrase.

An example of a syntactic nucleus in the noun phrase “the white dog” would be “dog”, which is the noun around which the article “the” and the adjective “white” come together.
