Answer
Eukaryotic genomes have several parts or aspects which affect replication: 1) linear chromosome ends either become shorter with each replication (they are inserted in membranes) or must be lengthened by telomerase; 2) having multiple chromosomes means that genome copying takes longer and must begin at many places at once; 3) the larger genomes of eukaryotes also require longer times for copying all of the DNA.
Work Step by Step
To answer this question, first list important differences between eukaryotic and bacterial genomes: linear chromosomes, genome size, telomeres. Then, simply describe what each of these means.
