Question

Which of the following statements is correct regarding the genomic DNA of bacteria?

• A. DNA is circular, not associated with histone proteins, and organised into a single chromosome
• B. DNA is linear, not coiled around histone proteins, and organised into a single chromosome
• C. DNA is circular, associated with histone proteins, and organised into two chromosomes
• D. DNA is linear, associated with histone proteins, and organised in two chromosomes

Answer 1

The correct option is A DNA is circular, not associated with histone proteins, and organised into a single chromosome

The genomic DNA of prokaryotes is circular and is characterised by the absence of histone proteins and is organised into a single chromosome. The region in prokaryotic cells that have DNA is referred to as nucleoid.
