Telomeres

An Introduction to DNA Transcription - ThoughtCo Eukaryotic cells also use reverse transcription to extend the end sections of chromosomes known as telomeres. The enzyme telomerase reverse transcriptase is responsible for this process. The extension of telomeres produces cells that are resistant to apoptosis, or programmed cell death, and become cancerous.
