Question

The genetic material of bacteria is known as
A. Gene
B. Chromosome
C. Genophore
D. Nucleohistone

Answer 1

A bacterium is a group of a microscopic living organism that is single-celled i.e. unicellular. These organisms can survive in large numbers in almost every environment on Earth. It can be found from deep-sea vents too deep below Earth’s surface, also present in the digestive tracts of humans.

Complete step by step answer:
Bacteria are a type of microscopic biological cell that can build a large domain of prokaryotic microorganism. Bacteria, a unicellular organism can be found in every environment on earth. They are the prokaryotic cell as it lacks a membrane-bound nucleus and other internal structures.
The contents of the bacterial cell are enclosed by a cell membrane, which is primarily composed of phospholipids. And at the outside of the cell membrane, there is the cell wall which is made of peptidoglycan.
The bacteria do not possess a membrane-bound nucleus. The genetic material is typically a single circular bacterial chromosome of DNA which is the nucleoid. The nucleoid is present in an irregularly-shaped region. It contains all or most of the genetic material of the bacterial cell. The genetic material of bacteria is known as genophore which is the DNA of a prokaryote. The chromatin is not present in the genophore. It has a double-stranded supercoiled DNA. Genophore can be either circular or linear.
The genetic material of bacteria or genophores is observed in the cytoplasm of the cell in the form of nucleotides. The chromosome with its associated proteins and RNA are present in the nucleotide.
Therefore, the correct option for the question is option C.

Additional Information:
There is a wide diversity found in shapes and sizes of bacteria. A cell of bacteria is approx. one-tenth of the size of eukaryotic cells. There is a great variety of shapes also. Most species of bacteria are either spherical or rod-shaped. There are also some bacteria as curved-shaped and coiled-shaped.

Note:
Bacteria is a type of microscopic cell which is single-celled. In every environment of the earth, their presence can be observed. Bacteria are prokaryotes because they do not have a membrane-bound nucleus. Therefore, their genetic material is a single circular bacterial chromosome of DNA which is the nucleoid. This nucleoid or genetic material of the bacteria is known as genophore which is present in the cytoplasm of the bacterial cell.
