Final answer:
Cdc13 is the protein that binds to telomere repeats and recruits Stn1 and telomerase, playing a key role in telomere maintenance.
Step-by-step explanation:
The protein that binds to the telomere repeats and recruits two other proteins, Stn1 and telomerase, is Cdc13. This binding is a crucial step in the maintenance of telomeres, which are repetitive nucleotide sequences at the ends of chromosomes. Cdc13 is specifically involved in the protection of telomeres in yeast and collaborates with Stn1 and Ten1 to form the CST complex which is involved in telomere maintenance and telomerase regulation.
