Week 3:

Evaluation of the wiki article on Biostasis:

This article is a stub and needs a considerable number of edits. As far as I can tell this topic is steal rather cutting edge as all of the relevant citations are from this year which means we will likely need more research in order to expand the article with authoritative research. Even if this is the case, the article could use some cleaning up. The first paragraph provides a definition of biostasis without an inline citation so it will likely need an edit and a citation to a reliable source. DukeTwicep commented in the talk page that there are two citations that direct to pages about Tardigrades that have nothing to do with the workings of biostasis which is a problem. There is very little information in this article that deals directly with a precise description of biostasis and how it works mechanistically. Instead the article concerns itself primarily with methods which produce biostastis. This is valuable information for the article, but I doubt it will meet encyclopedic standards. I imagine what this article needs most is more sources and informaion on the topic.

The article is okay but it needs work. I don't see any issues with plagarism. The writing is very clear and concise. But the topic isn't completely covered and there are not enough references. The coverage, however, is neutral and unbiased and very clear about what it's attempting to illuminate.

Week 5:

Added Citation to Anaphase; Schafer K.A. (1998-11). "The Cell Cycle: A Review". Veterinary Pathalogy. 35 (6): 461-478. doi:10.1177/030098589803500601. ISSN 0300-9858.

Week 6:

I've found some more fodder for my anaphase project. There's no content in the article about anaphase A and B, two stages within this part of the cycle, so I went and found an article about it found below. I'll likely edit in these concepts either as one comparative section with 2 or more paragraphs or as two separate sections. And In the second case I will likely find another article to fill out each section.

http://eds.a.ebscohost.com/ehost/detail/detail?vid=25&sid=699095a5-65ef-4703-90a2-dcca2f4c74b5%40sdc-v-sessmgr05&bdata=JkF1dGhUeXBlPXNoaWImc2l0ZT1laG9zdC1saXZl#AN=122076964&db=aph

It's also pretty apparent that the outlining of the protein interactions in the section titled "Relation to the cell cycle" is extremely bare bone. There's much room for broadening the scope of the article in this section especially with the article that I cited in last week's sandbox entry. However, I would question the need for this section at all as it doesn't exist in other similar articles. In fact, I'm inclined to edit the information in this section into the previous section to make the article more concise. The page on Metaphase for example, has a much more descriptive body excluding the "relation to the cell cycle" portion entirely. This format makes more sense as the concepts should be brought together directly only in the higher order pages, that is Meiosis and Mitosis, leaving this one particularly dedicated to Anaphase.

Week 7&8:

Anaphase A
Anaphase is characterized by two distinct motions. The first of these, Anaphase A, moves chromosomes to either pole of a dividing cell. Anaphase B involves the separation of these poles from each other. A combination of different forces have been observed acting on chromatin in Anaphase A, but the primary force is exerted centrally at an attachment site known as a kinetachore. Through the shortening of each kinetachore attached microtubule the primary force is produced at the midpoint of the chromosomes. This poses a problem regarding the structure of the microtubule-kinetachore attachment because possible locations of fiber degradation include the site of attachment itself. Theories proposed to solve this problem of attachment include the conformational wave model, the biased diffusion model or a hybrid model of both.

Other forces blow chromatin in some direction, most notably at the arms forming the octopi shape that's typical of mitotic division. Chromatid move both poleward and antipoleward in almost all dividing cells. Antipoleward motion is driven by external forces such as polar winds whereas poleward motion is driven by forces applied to the chromosome through the kinetachore attachment.

Anaphase B
The second part of anaphase is driven by its own distinct mechanisms. Force is generated by a combination of spindle-poles pushing against one another and a pulling of spindle-poles away from each other by motors attached to the cell cortex. Spindle pushing, or 'spindle elongation,' generates force on both spindle poles in equal measure as microtubules emanating from either pole push against a complimentary other through their intermediate crosslinks.

Week 9

Paul Sylvia Peer Review

What you wrote about Anaphase A and B is really well done, and explains them very well. In your content gaps, you wrote about how the section called “Relation to the cell Cycle” is very bare, but you didn’t say what you were thinking of doing about that in your contribution. You did go on to say that you were considering deleting it completely and adding information about metaphase. Is that what you’re going to do? Or are you just going to leave it as is? You only have two citations for what you added. Is that because you only checked two cites, or do those pages have the best information? I’m only asking because you have a lot written, and I would think that you would’ve gotten all of that information for several pages. Also with your cites I don’t think they are cited properly, but I’m pretty sure you know that and will fix them when you put them in your article.

Julie Barber Peer Review

Hey Julie, first of all, your formatting work is fantastic. This page is really well organized.

Prokaryotes: So I'm having trouble discerning what your citation here suggests. It's reference to the evolutionary stage of the prokaryote seems to suggest something that doesn't have much to do with cell division. Perhaps I'm confused, but then I would think that this section needs some more detail.

Anaphase. Your addition here looks great. Nice work.

Telophase: I'm sorry, but it looks as though the current page already has a solid citation for the nuclear membrane reformation at the end of telophase. It says, "Two nuclear membranes begin to reform and the chromatin begin to unwind." Although It looks like you have a nice broad citation for this part. Perhaps you could draw something else out if it related to telophase. For example, the current version says, "Two cells form around the chromatin at the two poles of the cell." So it's describing cytokinesis there without a citation or very much detail. You could probably use your citation for this and add some new info. Or, I'm sure, you could find something else.

Looking Good Julie, I don't think I'm going to be in tomorrow A.M. but feel free to email me if you want. paulsylvia20@gmail.com.
