Protists, unicellular organisms with diverse ecological roles, exhibit a range of chromosomal structures. Circular chromosomes are found in certain protists, contrasting with the linear chromosomes typically associated with eukaryotes. The presence of circular chromosomes in protists has implications for their genetic organization, genome evolution, and cellular processes such as DNA replication and segregation. This article explores the prevalence of circular chromosomes in protists, examining their characteristics, distribution across different protist groups, and the potential evolutionary advantages they confer.
