Answer

Difference Between Nucleus and Nucleoid

The nucleus is the important and largest cell organelle in a eukaryotic cell. A nucleus is a membrane-enclosed organelle that houses the genetic material of eukaryotes in DNA. The nucleus consists of protein fibers or the DNA inside chromatin fibers. Nucleoids contain the genetic material of prokaryotes in the cytoplasm. The nucleoids consist of a single chromosome. Let us look at more differences between the nucleus and nucleoid in the table given below.

Nucleus

Nucleoid

A nucleus is a membrane-bound structure in which eukaryotes store their genetic materials.

Nucleoid is a particular area in which prokaryotes store their genetic materials.

A nucleus is well organised and is large.

Nucleoid is poorly organised and is small.

A nucleus is surrounded by a double layer membrane called nuclear membrane which separates the nucleus from other cell organelles.

Nucleoid lacks a protective membrane.

A nucleus contains many chromosomes.

Nucleoid contains only a single circular DNA molecule.

A nucleus is a spherically shaped organelle.

Nucleoid is an irregularly shaped organelle.

Nucleoplasm and Nucleolus are present in the nucleus.

Nucleoplasm and Nucleolus are absent in a nucleoid.

It is composed of DNA, RNA, enzy
