Below Is a Diagram of DNA Replication as Currently Believed

Below is a diagram of DNA replication as currently believed to occur in E. coli. Arrows start from numbers and end at specific points. Answer the questions relating to the
locations specified by the numbers.
1() Which end (5' or 3') of the molecule is here?
2() Which enzyme is probably functioning here to deal with supercoils in the DNA?
3() Which enzyme is probably functioning here to unwind the DNA?
4() Which nucleic acid is probably depicted here?
5() What are these short DNA fragments usually called?
6() Which enzyme probably functions here to couple these two newly synthesized fragments of DNA?
7() Is this strand the leading or lagging strand?
8() Which end (5' or 3') of the molecule is here?
