what structures are found in the nucleus?

Answer 1

the nucleolus, DNA

Answer 2

In chemistry and physics, an atom is the smallest possible particle of a chemical element that retains its chemical properties. (Since until the advent of quantum mechanics dividing a material object was invariably equated with cutting it, átomos is usually translated as "indivisible".) Whereas the word atom originally denoted a particle that cannot be cut into smaller particles, the atoms of modern parlance are composed of subatomic particles:

Electrons, which have a negative charge and are the least massive of the three;

Protons, which have a positive charge and are about 1836 times more massive than electrons; and

Neutrons, which have no charge and are about 1839 times more massive than electrons.

Protons and neutrons make up a dense, massive atomic nucleus, and are collectively called nucleons. The electrons form the much larger electron cloud surrounding the nucleus.

Answer 3

Chromatin, nucleolus, nucleosomes.

Answer 4

chromosomes
