Question

4.DNA replication in eukaryotes is different from bacteria because (select the best answer below):

a. bacterial DNA replication involves more replication forks

b. only bacterial DNA replication uses the helicase enzyme

c. eukaryotes have larger genomes than bacteria

d. bacterial DNA replication does not involve Okazaki fragments

Answer 1

Answer :) Option c

The eukaryotic genomic DNA is larger than prokaryotic DNA and hence to replicate the DNA of eukaryotes, the cell uses different sites of replication i.e. replicons. Bacterial DNA has only one replicon i.e. the whole DNA. Helicase enzyme is present in eukaryotes too. Bacterial DNA also uses Okazaki fragments to replicate itself. Therefore, option c is the correct answer.
