Document Summary
Telomere is the end of the dna strand that had multiple repeating bases that the telomerase binds to. Now that telomerase has made and has added complimentary base pairs to the end the strand the dna can then begin to replicate at the newly formed three prime end. Telomerase adds dna to the end of chromosomes controlling the shortening caused my dna replication. Telomerase does not prevent the mechanism that causes your chromosomes to shorten; dna will shorten no matter what. What telomerase does is adds dna to the end of chromosomes such that the shorten doesn"t matter, its controlled. Your telomere is a way for your cell to tell how old it is, it isn"t a way to protect the more valuable dna it just tells the cell the age of the dna. Every time your dna replicates your telomere becomes shorter. Connection between mutations and dna replication is the primer on the leading strand.
