The end‑replication problem (telomere problem) exists in eukaryotic chromosomes and is characterized by the chromosomes shortening with each round of dna replication. select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes. 1) the rna primer is removed in a 3′ to 5′ direction. 2) dna ligase links the 5′ oh group of one fragment to the 3′ phosphate group of an adjacent fragment. 3) dna polymerase synthesizes dna from the phosphate end to the hydroxyl end. 4) dna polymerase requires a primer for dna synthesis. 5) the lagging strand is synthesized from the hydroxyl end to the phosphate end.
