Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Structure of ‘prokaryotic DNA’ is called
A
ribosome
B
cytoplasm
C
nucleoid
D
Plasma membrane
Explanation: 

Detailed explanation-1: -The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. Many prokaryotes also carry small, circular DNA molecules called plasmids, which are distinct from the chromosomal DNA and can provide genetic advantages in specific environments.

Detailed explanation-2: -Prokaryotic cells, such as bacteria, have a free-floating chromosome that is usually circular and is not enclosed in a nuclear membrane. Instead, the DNA simply exists in a region of the cell called the nucleoid.

Detailed explanation-3: -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. In contrast to the nucleus of a eukaryotic cell, it is not surrounded by a nuclear membrane.

Detailed explanation-4: -Nucleoid Meaning By definition, a nucleoid is a region within a prokaryotic cell that contains most or all of the genetic material. This material is called a prokaryotic chromosome. DNA is found in both the nucleus and nucleoid.

Detailed explanation-5: -Explanation: Plasmids are extrachromosomal small circular DNA that is present in bacterial cell, apart from the genomic DNA.
