The advent of genomic sequencing and annotations using bioinformatics has led to the realization that some of the long- held beliefs about prokaryotic genome structure were incorrect.Which of the following has not been refuted by modern bioinformatic discoveries?
A)Prokaryote genomes do not contain introns.
B)All bacterial genomes are circular.
C)Bacterial genomes are always smaller than eukaryotic genomes.
D)Prokaryotes have a single chromosome.

Question

Quizplus · Accepted Answer

Prokaryote genomes were traditionally thought to lack introns, but this has been challenged by discoveries of introns in some prokaryotes. However, the statement that prokaryote genomes do not contain introns has not been universally refuted by bioinformatics, as introns are still relatively rare in prokaryotes compared to eukaryotes. The other options (B, C, D) have been refuted or shown to be too simplistic by modern genomic studies. For example, some prokaryotes have been found to have linear chromosomes or multiple chromosomes, bacterial genome sizes can vary widely, and not all bacterial genomes are circular.
