1. When the RNA primer is removed from the 5' end of the lagging strand, a strand of DNA remains unreplicated
2. Telomerase binds to the overhanging section of ss DNA.
3. Telomerase adds nucleotides to the end of the parent DNA, extending it
4. Telomerase moves down the DNA strand and adds additional repeats
5. Primase, DNA polymerase, and ligase then synthesize the lagging strand in the 5' - 3' direction, restoring the original length of the chromosome
