The role of the DNA (deoxyribonucleic acid) polymerase in DNA replication . Given: DNA replication is a biological process that occurs in all living organisms and copies their DNA. Introduction: The first evidence of the existence of an enzymatic activity capable of synthesizing DNA came in 1958 with the discovery of Escherichia coli Pol I by A. Kornberg and colleagues. The discovery of several other polymerase activities soon followed, and it was realized that they possessed significantly different properties. The different types of DNA polymerases have been found in a single organism, for example, three (DNA Pol I, II, and III) in E. coli or five (DNA Pol α, β, γ, δ, and ɛ) in higher eukaryotes, which are believed to perform a specialized in vivo function.

Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding? Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…
