Which of the following statement about DNA polymerase of eukaryotes is NOT true:()
A. DNA pol α/primase are involved in initial synthesis of the nascent strand.
B. DNA polδ and ε are mainly responsible for the synthesis of DNA chains.
C. Replacement of DNA polymerase could happen during DNA synthesis process.
D. There are five kinds of DNA pol:α、β、γ、δ and ε in eukaryotes

In prokaryotes, filling the gaps generated by DNA replication or DNA repair mainly depends on ()
A. nuclease H
B. DNA polymerase I
C. DNA polymerase II
DNA polymerase α
E. DNA polymerase β
The correct statement about DNA polymerase III of prokaryotes is:()
A. with the activity of 3’→5’ exonuclease
B. with the activity of 5’→3’ exonuclease
C. with the activity of 3’→5’ polymerase
D. NTP as the substrate
E. only add substrate in the 3’ end of deoxyribonucleic acid
In eukaryotes, DNA pol α and primase can form a complex, to initiate primer synthesis and replacement of polymerase, then DNA pol α continue to synthesize the leading strand.()
If the DNA polymerase in E.coli lost its function of 3’→5’ exonuclease, the synthesis of DNA would be slowed down, while the fidelity of DNA would not be affected.()
