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.
1 The literature review is not merely a list of every item and resource with any possible relation to your topic, no matter how tenuous. 2  It focuses on those resources and materials that are directly relevant to the addressing of your topic, and as such, is highly selective. 3  on a particular question or area of research.
