Individual Assessments

Lab 1

1. What are the key cell biology journals?

The Journal of Cell Biology

BMC Cell Biology

Cell

Journal of Cell Science

Molecular Biology of the Cell

2. Which journals allow reuse of their published content?

The Journal of Cell Biology

BMC Cell Biology

Public Library of Science

Lab 2

1. Which chromosomes contribute to the nucleolus?

The nucleolus contains repeats of ribosomal RNA genes on chromosomes 13, 14, 15, 21 and 22.

2. Identify and add a link to your page of a recent cell biology article using confocal microscopy.

Biotherapeutic target or sink: analysis of the macrophage mannose receptor tissue distribution in murine models of lysosomal storage diseases.



Lab 3

1. Find the SDS information for chloroform and identify the hazards associated with this chemical.

Chloroform is harmful when inhaled, and in high concentrations may even be fatal. It is a chlorinated hydrocarbon, which toxic when swallowed, and with repeated exposure may cause dermatitis and reproductive harm. May also be a potential human carcinogen with repeated exposure.

Lab 4

1. Identify a commercial supplier of an antibody that relates to your group project topic.

Millipore is a commercial supplier of the antibody 'Anti-Connexin 43, C-terminus' related to gap junctions. This specific connexin is able to recognize proteins who have a molecular weight between 43-47kD from Western blots of mouse fibroblasts as well as Cx43 in a variety of organisms.

2. In mitochondria, where is the gene located that encode Cytochrome C and what keeps this protein trapped within the mitochondria?

The CYCS gene encodes for Chromosome C. This gene is located from base pair 25,158,269 - 25,164,979 on chromosome 7. It is associated with the initiation of apoptosis as well as being part of the electron transport chain in the mitochondria. The mitochondrial membrane (in particular- the outer membrane) is reponsible for keeping this protein trapped within the mitochondria to function effectively.


Lab 6

1 a) What are the changes in phenotypes that you observe between group A and group B?

- In Genotype A, alot more branching and processes are seen. More branching therefore leads to more interaction between the cells. The processes also fluoresce more brightly as compared to Genotype B which are less brightly stained. Genotype B presents much less branching and processes and therefore have less interaction between each other.

b) How does Tm4 mediate these changes?
