The function of highly repeated satellite DNA sequence at the end of an eukaryotic chromosome is to protect the
Correct Answer
Option A is the correct answer.
Detailed Explanation
Highly repeated satellite DNA sequences at chromosome ends form telomeres. Their primary function is to protect the ends from deterioration or from fusion with other chromosomes, and they prevent the loss of essential genetic material during DNA replication, as the end-replication problem would otherwise cause shortening.
Hint
Think about the structure that solves the 'end-replication problem' and prevents chromosome fusion.
