Final answer:
Telomeres are structures found only at the ends of linear chromosomes in eukaryotic cells and are not present in prokaryotic cells with circular chromosomes.the answer is false )
Step-by-step explanation:
The statement 'Telomeres are usually found in both eukaryotes and prokaryotes' is FALSE. Telomeres are distinctive structures found at the ends of linear chromosomes in eukaryotic cells. Their main function is to protect the end of the chromosome from deterioration and fusion with neighboring chromosomes. In contrast, most prokaryotic organisms, such as bacteria, have circular chromosomes that do not require telomeres.
