During the process of transcription, the polymerase must handle several distinct polynucleotide chains: the double-stranded DNA ahead of the polymerase, the single-stranded template DNA, the nontemplate DNA strand, and the freshly-synthesized mRNA. How does the polymerase keep each of these strands--as well as the incoming ribonucleotides needed for the polymerase reaction--separate?

Which of the followings statements are true about DNA polymerase? 1.) It can only go in one direction, meaning the lagging strand can't be synthesized continuously. 2.) It cannot start a DNA strand from scratch, so another enzyme is needed to create "primers" as a starting point. 3.) It cannot copy epigenetic marks (such as methyl groups) on its own; these must be "copied" onto the daughter DNA strand by other enzymes after DNA replication. 4.) All of the above
