Question

Write a summary and your own thoughts on the news article you chose in Lesson Activity 3. It is allowed to expand on your previous response of Lesson Activity 3 and use the same reference again. You may choose a new article if desired using the same criteria

For your summary, describe the main discovery of the article. Make the cellular or molecular aspects clear in your summary. Cite your article in the text as appropriate. Review at least one other resource associated with the article from outside the class (not your text or lab book) such as CDC.gov, WebMD.com, or another article. Add this information to your summary, such as an introduction or related to the discovery, and cite/reference the additional article. Citations and bibliographical references should be in APA or similar format. The whole summary should be a minimum of five sentences in one paragraph.

Add a second paragraph that briefly describes your thoughts on the article and discovery. This should be a minimum of two sentences. No other replies to other student posts are required, only optional.

This is the article

I have chosen an article from science daily published on June 8,2017. The article focuses on the evolutionary divergences in the emergence of antibiotic resistance in bacteria or cancer in humans. The article highlights the fact that conditions common in nature strongly influence the pattern of genetic variation and consequently the evolvability of traits dependent on particular mutations.

Reference: University of Sydney. (2017, June 8). The road not taken: Do stress-specific mutations lead down different evolutionary paths?. ScienceDaily. Retrieved June 21, 2017 from www.sciencedaily.com/releases/2017/06/170608145526.htm

Explanation / Answer

Solution) As you have gone through the article, you must be clear with the discovery and the experimentation the researchers have followed. below is the short summary of one paragraph for this article and the second paragraph reflects my own personal thoughts on the article and discovery.

Summary - This research was carried out by Maharjan and Ferenci, where they discovered different environments may have different sets of variations (non-uniform distribution). detailed analysis of mutations related to different nutritional environment suggested that the kind of variations available to organisms are strongly influenced by available nutritional factors. while oxygen, nitrogen, and iron starvation had no such impact on the rate of mutation, but Carbon and phosphorus starvation were able to induce a greater impact on the total mutation rate (four- to nine- fold increase in total mutation rate per locus per generation). Fe and O starvation showed higher IS mutations (Insertion Sequence transpositions) as compared to N, C and lowest mutations under the P limitation. also, BPS (Base Pair Substitutions) overproduction was induced by P limitation mainly due to GC toTA transversions and GC to AT. these discoveries strongly suggested that nutrition determines the mutation.

Personal thoughts - This is a great non-conventional discovery that the mutations/genetic variations are randomly distributed and they are strongly influenced by the available nutritional factors. specifically, the detailed molecular aspect related with different nutritional factors provided an insight into unexplained genome architecture. this research can be further extended to explain the complex evolution of genomic architecture in primitive life forms.
