Eukaryotic DNA replication faces the 'end-replication problem' at the telomeres. Which enzyme solves this by extending the ends of chromosomes?
Show answer and explanation
Correct answer: Telomerase
Telomerase is a ribonucleoprotein that carries its own RNA template. It adds repetitive DNA sequences to the 3' ends of chromosomes, preventing the loss of vital genetic information during successive rounds of division.
