Question

Which type of DNA is found in bacteria?

Answer 1

Bacteria :

1. Bacteria is a prokaryotic unicellular organism.
2. It lacks membrane-bound organelles like mitochondria, Golgi apparatus.
3. It lacks a true nucleus, the genetic material is not bound by a nuclear membrane. Hence, it is called a nucleoid.

Bacterial DNA:

1. Bacteria have a single circular chromosome that is located in the cytoplasm in a nucleoid.
2. The genetic material is free, irregular, thin fibrillar, double-stranded circular DNA.
3. Bacterial DNA is not associated with histone proteins and does not coil to form well-defined chromosomes during multiplication.
