Answered by The Community. Making the world better, one answer at a time. Helicase and RNS polymerase are used in the nucleus. The helicase enzyme is used to unzip the Dna strand in order for the RNA polymerase to copy the genetic code from the Dna strand and copy it to the newly formed mRNA strand.nswered by The Community.

A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.
The purpose of a literature review is to: 1  Place each work in the context of its contribution to understanding the research problem being studied. 2  Describe the relationship of each work to the others under consideration. 3  Identify new ways to interpret prior research. 4  Reveal any gaps that exist in the literature.
