The enzyme telomerase solves the problem of replication at the ends of linear chromosomes by which method?

causing linear ends of the newly replicated DNA to circularize
adding a single 5′ cap structure that resists degradation by nucleases
adding numerous GC pairs which resist hydrolysis and maintain chromosome integrity
adding numerous short DNA sequences such as TTAGGG, which form a hairpin turn
causing specific double strand DNA breaks that result in blunt ends on both strands

None of the above, but put:
adding numerous short DNA sequences such as TTAGGG, which form a hairpin turn

It adds the TTAGGG segments, but there’s no hairpin turn involved. Double-stranded DNA doesn’t do hairpins. It’s linear.
