Final answer:
Repetitive DNA is most likely to be found in the centromeres and telomeres of chromosomes. The centromere is a highly condensed region where sister chromatids are attached to each other. The telomeres protect coding sequences from being lost as cells continue to divide.
Step-by-step explanation:
Repetitive DNA is most likely to be found in the centromeres and telomeres of chromosomes. The centromere is a highly condensed region where sister chromatids are attached to each other. It contains proteins called kinetochores where spindle fibers attach during mitosis. The telomeres, on the other hand, are located at the ends of the chromosomes and consist of noncoding repetitive sequences that protect coding sequences from being lost during cell division.
