Hey @caffeinatednurse. Correct me if Iām wrong but I believe telomeres are a primarily double-stranded DNA sequence, which means they have two complementary strands:
One strand is the sense strand (also called the coding strand), and it contains the repeating TTAGGG sequence.
The complementary strand, which pairs with the sense strand, contains the AATCCC sequence.
Therefore, this repeating sequence is 50% GC bonds. This is comparatively GC rich to the average of the rest of the human genome.
There are three hydrogen bonds between G and C and two hydrogen bonds between A and T. The stronger bonding between G and C due to the number of hydrogen bonds is what contributes stability.
Excuse my stupidity. You are actually correct!
