How are telomeres rich in guanine not other nitrogenous bases am confused?

@Lebogang: Telomeres are made up with the nucleotides TTAGGG. There are many groups of TTAGGG that make up the nucleotide, and GGG, or guanine guanine guanine, shows up the most.

Telomeres have random GT-rich repeats such as TTGGGG in tetrahymena and TTAGGG in human beings. G-quadruplex (guanine-rich region).
