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. WebScience Biology A Eukaryotic cell packages it's DNA into chromosomes to prepare for mitosis or meiosis. Why does it do this? O a. To organize and protect the DNA before the cell divides O b. To form chromosomes O c. To give more DNA to one daughter cell that needs it O d. To divide the DNA and proteins into 25% allotments
