The answer is yes, some prokaryotes have linear DNA. While most prokaryotes are known for having circular DNA, this isn't universally true.
Linear vs. Circular DNA in Prokaryotes
Traditionally, prokaryotes were characterized by having a single, circular chromosome. E. coli is a prime example. However, our understanding has evolved.
Evidence of Linear DNA in Prokaryotes
Recent studies have shown that some prokaryotes possess linear chromosomes in addition to, or instead of, circular ones. According to research, some prokaryotes contain as many as four linear or circular chromosomes.
Implications
The presence of linear DNA in certain prokaryotes challenges the long-held belief that all prokaryotic genomes are circular. This finding expands our understanding of prokaryotic diversity and genomic organization.
