A) I think your assignment is good. You've used a lot of sources which has made the depth of your understanding really good. It would be good if there was some in-text referencing so we can see where the information came from, so that we can have a look at the original text if we want a deeper knowledge than what you have given us. The only problem I was able to pick up is that there is no summary on the images you have uploaded. Other than that, its a good page.

B) The content is well structured. It is good to link the topic to group project, eg,"the main function of peptidoglycan is to regulate the cellular shape... hold together the shape of cell ...allows to have some flexibility". But i found the section regarding to metabolism of the protein such as enzymatic and gram staining is a bit too lengthy, might consider condense the section. It's good to provide glossaries makes the page easy to read. In addition, you might like to consider devote a section on the current development/research regarding to this particular protein. Overall, i consider this is a well structured page.

C) I can see a good consise and informative introduction to the topic which is good. I have the feeling that structure part of your research can be outlined better and with more reference to the image. There were a lot of new words that i came across while I was reviewing this, however you put up a good solid glossary page which explained most of the new terms that I came across. Finally I think my understanding of the topic would be more easier with more illustrations and diagrams. But overall you have produced a good solid report on your research. z3224430

D) Overall very informative page about Peptidoglycan. I found the paragraph format a bit difficult to follow, made it all seem very lengthy and detailed. I had to read things through a few times to understand. Perhaps you can organize some parts of the page into dot points? Or add more subheadings? Such as under gram staining:

Gram positive bacteria

  • forms a stronger peptidoglycan wall by creating a three dimensional mesh work with multiple layers
  • their walls tend to be thicker, stronger and more rigid
  • contain teichoic acid which is covalently linked to the peptidoglycan layer and lipoteichoic acids linked to the cell membrane.
  • ... etc.

Just a suggestion though, I'm more of a dot-point kinda person =)


E-Hi there… in terms of word limit, I think it exceeds the max of 1000 words. So maybe you should try and cut unnecessary stuff. In my opinion it’d be good to explain gram stain procedure in dot point forms. Also, please make sure that references are cited within the written text. Also, try and find more recent research paper. It’d be great to include any current research that has been done on peptidoglycan lately. Other than that I have to say you have done well!! Z3191358



--Mark Hill 10:04, 20 April 2009 (EST) Well done you are on track with your online work.

--Mark Hill 18:42, 19 March 2009 (EST)Thank you for your feedback on the nucleus, I did not really get a feeling of whether these are concepts you had never heard of before, or were just listing relevant points?

Homework assignments are now on this discussion page so that it can be separated from my individual project.

The Nucleus

  • stores all genetic information for the cell
  • uses pores as a way of transporting mRNA and other materials
  • membrane enclosed area
  • produces ribosomes

Exocytosis

I think the most difficult part of the exocytosis lecture was understanding the functions of the golgi apparatus. I haven't learned much about this topic before and it seems to have an important function for the cell.

Mitochondria

The mitochondria of the cell contain high amounts of energy as ATP. The muscles in the body, flagella and sperm tail require a high amount of energy from mitochondria. Cell division also requires a lot of energy as well as cellular respiration to produce muscle movements. More ATP is created for the mitochondria to store when oxygen is present.

Cell Junctions

The term CAM is generally given to the cellular adhesion molecules and vary in types. N-CAM and Ng-CAM is a neural cell adhesion molecule and a neural glia cell adhesion molecule used in cell to cell adhesion of mostly neurons, glial cell, and natural killer cells. I-CAM is an intercellular adhesion molecule used for cell to cell adhesion to migrate cells in and out of tissue. L-CAM is a liver adhesion molecule which is a cell to cell adhesion molecule in the liver.

Cytoskeleton

Desmosomes are the adhesion spot between two cells and can be found in the stratum spinosum layer of the skin.

Confocal Microscopy

The two main types of generating confocal microscopy is through laser and spinning disc.

Cell Cycle

S Phase is also known as the Synthesis Phase where DNA replication takes place during the cell cycle.
