Moreover, bacterial chromosomes do not undergo the … WebRepetitive regions at the very ends of chromosomes are called telomeres, and they're found in a wide range of eukaryotic species, from human beings to unicellular protists. Telomeres act as caps that protect the internal regions of the chromosomes, and they're worn down a small amount in each round of DNA replication.
