What is the meaning for nucleus?

Answer 1

Biology. a specialized, usually spherical mass of protoplasm encased ina double membrane, and found in most living eukaryotic cells, directingtheir growth, metabolism, and reproduction, and functioning in thetransmission of genic characters.

Answer 2

A general definition would be:

a central part about which other parts are grouped or gathered; core

As it applies to Biology:

It stores DNA that has information on how to make all of the cells proteins.
Nucleolus are one or more circular regions inside the nucleus that are visibly distinguishable from the rest.

Answer 3

• Physics: the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass.

• Biology: a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.

• Astronomy: the solid part of the head of a comet.

• Anatomy: a discrete mass of gray matter in the central nervous system.

Answer 4

In biology, the nucleus is a membrane-bound organelle that contains the genetic material (DNA) of a cell. It serves as the control center of the cell, regulating gene expression and coordinating cellular activities.

Answer 5

the control center of a eukaryotic cell that directs the cells activities and contains the information that determines the cells form and function

Answer 6

a nucleus is defined as the spherical, oval or circular, densely charged centre of a living cell in a living organism

Answer 7

An atom's nucleus is the small body at the center of the atom where most of the mass is contained.

The Nucleus contains positively charged protons and electrically neutral neutrons.

Answer 8

It's the brain of a cell.

Answer 9
