Nucleus

"Nucleus" Meaning

The nucleus is the central part of an atom, composed of protons and neutrons. It is the dense innermost part of the atom and contains most of the atom's mass. The nucleus is surrounded by a cloud of electrons that orbit around it.

"Nucleus" Similar Words

Nucleosomes

Nucleosomes are the basic structural units of chromatin, the material that makes up the chromosomes within the nucleus of eukaryotic cells. A nucleosome consists of a segment of DNA wrapped around a core of eight histone proteins: two copies each of histones H2A, H2B, H3, and H4. The histone core forms a disc-like structure, and the DNA is wrapped around it in a manner similar to a spool of thread, resulting in a repeating structure called a nucleosome repeat. The nucleosomes are linked together by stretches of DNA, forming the chromatin fiber, which is highly compacted to fit inside the nucleus.

Nucleosynthesis

Nucleotidase

Nucleotidase is a type of enzyme that catalyzes the hydrolysis of nucleotides, such as nucleic acid monomers, into nucleosides and phosphate groups. In other words, it breaks down nucleotides into simpler components, playing a crucial role in the metabolism of nucleic acids.

Nucleotide

Nucleotides

Nucleotides are the building blocks of nucleic acids, such as DNA and RNA. They are composed of three components: a nitrogenous base, a five-carbon sugar, and a phosphate group. The nitrogenous base can be one of five different bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). Nucleotides are linked together through the sugar and phosphate groups to form a chain, which makes up the structure of DNA and RNA.

Nucleotidic

Relating to or involving nucleotides, which are the building blocks of nucleic acids such as DNA and RNA. A nucleotidic acid is a molecule composed of nucleotides.

Nucleotidyl

Nucleotidyl refers to a group of nucleotides that are linked together through their phosphate groups. In chemistry, nucleotidyl is the suffix used to describe a molecule that consists of a nucleotide covalently attached to another nucleotide or a nucleotide-rich molecule, such as RNA or DNA.

Nucleotomy

Nucleotomy is a surgical procedure that involves the removal of the nucleus of a nucleus-containing cell, such as a lens nucleus in the eye.

Nucleuses

Nuclide

A nuclide is a species of atom with a specific number of protons in its atomic nucleus, which defines the element, and a specific number of neutrons, which defines the isotope of that element.

Nuclides

Nucleides refer to the various isotopes of an element that have the same atomic number but a different mass number due to a different number of neutrons in the atomic nucleus.
