举一反三
- Topoisomerase II catalyzes the transient breaking and rejoining of two strands of duplex DNA which allows the strands to pass through one another, thus altering the topology of DNA.
- Which<br/>of the following statement about DNA polymerase of eukaryotes is NOT<br/>true:() A: DNA<br/>pol α/primase are involved in initial synthesis of the nascent<br/>strand. B: DNA<br/>polδ and ε are mainly responsible for the synthesis of<br/>DNA chains. C: Replacement<br/>of DNA polymerase could happen during DNA synthesis process. D: There<br/>are five kinds of DNA pol:α、β、γ、δ<br/>and ε in eukaryotes
