Which statement is TRUE?
Phantasy [73]

Answer:

A

Explanation:

All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.

The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).

The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.
