The endāreplication 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 3ā² to 5ā² direction. 2) dna ligase links the 5ā² oh group of one fragment to the 3ā² 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.
