What are the 4 stages of DNA telomere replication?

1. Extension of the 3′ overhang by telomerase: Telomerase adds repetitive nucleotide sequences to the 3′ end using an RNA template.
2. Synthesis of the complementary strand: DNA polymerase synthesizes the complementary strand to elongate the telomere.
3. Removal of the RNA primer: RNA primers used during replication are removed, creating gaps.
4. Re-sealing by ligase: DNA ligase seals the gaps in the DNA backbone, ensuring telomere integrity.
