D)prions.

Question

Quizplus · Accepted Answer

Nonchromosomal DNA molecules found in a bacterial cell are called plasmids. They are small, circular DNA molecules that replicate independently of the bacterial chromosome. Plasmids often carry genes that provide advantages to the bacterium, such as antibiotic resistance, virulence factors, or the ability to metabolize unusual substances. Endospores are dormant structures that some bacteria can form when conditions become unfavorable, but they are not DNA molecules. Transposons are segments of DNA that can move from one location to another within the genome, but they are still part of the chromosomal DNA. Prions, on the other hand, are neither DNA nor molecules in the traditional sense; they are misfolded proteins that can cause disease.
