Answer:
The nucleoid (meaning nucleus-like) is an irregularly shaped region within the cell of a prokaryote that contains all or most of the genetic material, called genophore. In contrast to the nucleus of a eukaryotic cell, it is not surrounded by a nuclear membrane

Answer:
Define nucleoids in 2 to 3 sentences.
❥ In some organisms like bacteria, the nuclear region of the cell may be poorly defined due to the absence of a nuclear membrane.
❥ Such an undefined nuclear region containing only nucleic acids is called nucleoid.
❥ Such organisms, whose cells lack a nuclear membrane, are called prokaryotes ( Pro = primitive or primary; karyote ≈ karyon = nucleus).
❥ Organisms with cells having a nuclear membrane are called eukaryotes.
