Lab 1 Questions
1. What are the key cell biology journals?
- The Journal of Cell Biology
- BMC Cell Biology
- Nature Journals
- Trends in Cell Biology
2. Which journals allow reuse of their published content?
The Journal of Cell Biology and BMC Cell Biology.
3. Show some formatting.
4. Internal link: First lab
5. External link: The Journal of Cell Biology
Lab 2 Questions
- Pubmed: Pubmed
- Cell nucleus: Search MBOC Cell Nucleus
- Nucleolus: Search MBOC Nucleolus
1. Which chromosomes contribute to the nucleolus?
The tips of five chromosomes contribute to the nucleolus, these are chromosomes 13, 14, 15, 21 and 22. These chromosome sections contain 180 rRNA genes which function to produce ribosomes needed for protein synthesis in the cytoplasm.Nucleolus Pubmed Nucleolus
2. Identify and add a link to your page of a recent cell biology article using confocal microscopy.
Article using confocal microscopy: Shear bond strength, failure modes, and confocal microscopy of bonded amalgam restorations
Lab 3 Questions
1. Find the SDS information for chloroform and identify the hazards associated with this chemical.
- Harmful if swallowed.
- Irritant to the skin.
- May have a carcinogenic effect.
- Prolonged exposure by inhalation or swallowing will have serious health effects.
2. You will need to upload an image and add it to your page, with the reference and copyright information with the image.
HGM reveals sub-cellular detail in the living mouse zygote.
Lab 4 Questions
1. Identify a commercial supplier of an antibody that relates to your group project topic.
Atlas Antibodies: Rabbit Anti-Human AJAP1 Polyclonal Antibody, Unconjugated. 
2. In mitochondria, where is the gene located that encode Cytochrome C and what keeps this protein trapped within the mitochondria?
The gene for Cytochrome C called the CYCS gene is located on chromosome 7. 
The Cytochrome C protein is located on the inner membrane of the mitochondria. It is kept within the mitochondria due to its attachment to the membrane by the protein cardiolipin and is only released to the cytosol when apoptosis begins, this release is regulated by Bcl-2 family proteins.
Lab 6 Questions
A = Fan
B = Broken fan
C = Stumped
D = Pronged
E = Stringed
F = Pygnotic
1. What are the changes in phenotypes that are observed between group A and group B?
- Phenotype Fan - Tm4 group reduced by about 11%
- Phenotype Broken Fan - Tm4 group reduced by about 30%
- Phenotype Stumped - Tm4 group increased by about 17%
- Phenotype Pronged - Tm4 group increased by about 26%
- Phenotype Stringed - Tm4 show only slight increase of about 3%
- Phenotype pygnotic - Tm4 only show very slight decrease about 1%
Most common phenotype for Tm4 was stumped and pronged and most common phenotype for the control was fan and broken fan.
2. How does Tm4 mediate these changes?
Lab 9 Questions
1. Identify from one of the cell line repositories: a neural cell line and a muscle cell line.
Neural cell line: CRL-2299 from ATCC 
Muscle cell line: CRL-1446 from ATCC 
2. Identify the species and growth conditions for these cell lines.
Neural cell line: CRL-2299.
Organism = Mus musculus (mouse).
Morphology = epithelial.
Organ = brain
Strain = BALB/c
Tissue = cerebral cortex
Disease = endothelioma
Cell Type = endothelialpolyoma middle T antigen transformed
ATCC complete growth medium = The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Temperature = 37.0°C
Atmosphere = air, 95%; carbon dioxide (CO2), 5%
Muscle cell line: CRL-1446
Organism = Rattus norvegicus (rat)
Morphology = myoblast
Source = myoblast
Strain = BD1X
Organ = heart
Tissue = myocardium
Growth medium = The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Group 1 Synaptic Junctions
- Introduction is good since you give a good outline about the nervous system and what a synaptic junction is, could say a bit about what the page is going to outline aswell. Big picture like that at the beginning draws the reader in, maybe in the intro write what its actually showing.
- Good use of pictures throughout the project page to break up the text and keep the reader interested.
- History is detailed but is there anything occurring from 1981-present?
- Introduction, history, neurotransmitters headings need referencing!
- Description of what a synaptic junction is is very clear and easy to understand, especially with the supporting pictures.
- I dont know what the point of the gallery at the bottom is, those pictures would be more effective put throughout the page.
- Glossary needs to be added to, every scientific word should be explained here, also should be listed alphabetically.
- The diseases headings should be bolded more and maybe use some dotpoints in this section to make it easier to read, or put it in a table.
- Overall, good project headings and pictures.
Group 2 Gap Junctions
- The introduction gave a good overview of all junctions which gives a good idea of what a junction is before detailing specifically what a gap junction is.
- Detailed history shows good research.
- Good array of pictures throughout the whole page, breaks up the information well.
- Comparison table is very detailed and shows a good amount of research as well as the diseases section which is very interesting especially with the addition of pictures.
- Glossary needs to be added to.
- The choice of content, headings and sub-headings, diagrams and tables show a good understanding of the topic area.
Group 3 Tight Junction
- Very good introduction, giving a good overview of all junctions and then specifically what a tight junction, very informative for the reader. But maybe write a bit more about tight junctions than the other junctions to emphasize what your page will be about.
- Good history section, is there anything beyond 2005?
- Maybe in structure could bold some key words like the main proteins occludin and claudin to emphasize this to the reader like you have in molecular components. Maybe make molecular components a subheading under structure as that what your essentially talking about. Use of dot points in this section is very useful.
- Could split the information in function and "Classification of Epithelia Using Tight Junctions" into dot points to make is easier to read, or even just smaller paragraphs as the big blocks of information is more difficult to take in.
- Diseases is very well researched and detailed but how are these diseases caused?
- Glossary needs to be expanded, every scientific term in the page should be explained here.
- Overall the page is very well researched and presented with a good balance of pictures.
