Answer
The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn.
Explanation
The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn. Telomerase is an RNA dependent DNA polymerase means an enzyme that can make DNA using RNA as a template. The ends of linear chromosomes called telomeres that protect genes from getting deleted as cells continue to divide. The telomerase enzyme attaches to the end of chromosome complementary bases to RNA template are added on 3 ends of the DNA strand.
