Concept explainers
To explain: The contribution of the plus-end-directed motor proteins and minus-end-directed motor proteins that bind to interpolar microtubules that determine the spindle length at the overlap region of the mitotic spindle.
Concept introduction: Motor proteins are the bridges between two microtubules. Microtubules are involved in segregation of the sister chromatids during anaphase of the mitosis. There are two types of motor proteins; Dynein and Kinesin. Dynein is retrograde transport that is from positive end to the negative end or minus-end- directed motor protein. Kinesin is anterograde transport that is from the negative end to the positive end or plus-end- directed motor protein. The motor proteins play a vital role in the determination of the spindle length. The motor proteins move on the tubulin proteins that include the sub types α, β and γ tubulins that

- 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.
