The most famous cancer cells are called HeLa cells. They're named HeLa cells after the young woman whose cervical cancer cells were biopsied to create this immortal line of cells: Henrietta Lacks. Her cells are still used to today in cancer research.
Side note: Her cells were used WITHOUT her consent and without any type of compensation for her contribution. Her case has been a big source of debate in the biomedical ethics community about consent and racial disparities in healthcare.
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.
