Choose the best explanation. Question 2 options: Helicase creates the replication fork; primase keeps the single strands from closing shut. Helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting. Ligase creates the replication fork; DNA polymerase II keeps the single strands from reuniting.

- Fill in the blank spaces below with the most appropriate terms. The word bank is not provided. DNA replication in bacterium Escherichia coli begins at a site in the DNA called At the replication fork, the strand is synthesized continuously while the strand is synthesized discontinuously (in fragments). The new DNA strand, which is synthesized discontinuously, initially consists of short DNA pieces that are called A short RNA primer at the beginning of each of the DNA fragments is synthesized by an enzyme called and this RNA primer is later removed by the enzyme called using its activity. Single-strand breaks (nicks) that are left behind in this process are sealed by the enzyme called A Moving to another question w!l save this resporse Quebon 4 InWhich of the following enzymes can break, and rejoin, phosphodiester bonds during the normal DNA replication process in the chromosomes of E. coli cells? single-stranded binding proteins RNA polymerase topoisomerase DNA helicase DNA ligaseAnswer the following questions with regards to DNA replication:1.
