Examples of symbiosis
Parasitism is a type of non mutual relationship between organisms of different species where one organism, the parasite, benefits at the expense of the other, the host. (Wikipedia.com) http://en.wikipedia.org/wiki/Parasitism
a relationship between two species of organisms in which both benefit from the association. (Dictionary.com) http://dictionary.reference.com/browse/mutualism
commensalism is a class of relationship between two organisms where one organism benefits but the other is neutral (there is no harm or benefit)(Wikipedia.com)http://en.wikipedia.org/wiki/Commensalism

The Habitable Planet
1) What assumptions does this model make about co-dominance as well as the general terrain of the ecosystem?
2) Do you find one producer to be dominant? Why might one producer be dominant over another?

Cloning
Who has the right to have children, no matter how they are created? Who doesn't? Why?
People who can't have kids should have the right to have children because it wouldn't be fair.I don't think there should be anyone who shouldn't have the right to have kids.

BLAST GENE
Gene Sequence 3:
most common caused disease:Alzheimer Disease
Description:Alzheimer's disease (AD) patients with an inherited form of the disease carry mutations in the presenilin proteins (PSEN1 or PSEN2) or the amyloid precursor protein (APP). These disease-linked mutations result in increased production of the longer form of amyloid-beta (main component of amyloid deposits found in AD brains). Presenilins are postulated to regulate APP processing through their effects on gamma-secretase, an enzyme that cleaves APP. Also, it is thought that the presenilins are involved in the cleavage of the Notch receptor such that, they either directly regulate gamma-secretase activity, or themselves act are protease enzymes. Two alternatively spliced transcript variants encoding different isoforms of PSEN2 have been identified
Gene Sequence 6:
most common caused disease/description:The protein encoded by this gene is a negative regulator of the cell cycle and was the first tumor suppressor gene found. The encoded protein also stabilizes constitutive heterochromatin to maintain the overall chromatin structure. The active, hypophosphorylated form of the protein binds transcription factor E2F1. Defects in this gene are a cause of childhood cancer retinoblastoma (RB), bladder cancer, and osteogenic sarcoma. [provided by RefSeq, Jul 2008]
Gene Sequence 8:
most common caused disease/description:The dystrophin gene is the largest gene found in nature, measuring 2.4 Mb. The gene was identified through a positional cloning approach, targeted at the isolation of the gene responsible for Duchenne (DMD) and Becker (BMD) Muscular Dystrophies. DMD is a recessive, fatal, X-linked disorder occurring at a frequency of about 1 in 3,500 new-born males. BMD is a milder allelic form. In general, DMD patients carry mutations which cause premature translation termination (nonsense or frame shift mutations), while in BMD patients dystrophin is reduced either in molecular weight (derived from in-frame deletions) or in expression level. The dystrophin gene is highly complex, containing at least eight independent, tissue-specific promoters and two polyA-addition sites. Furthermore, dystrophin RNA is differentially spliced, producing a range of different transcripts, encoding a large set of protein isoforms. Dystrophin (as encoded by the Dp427 transcripts) is a large, rod-like cytoskeletal protein which is found at the inner surface of muscle fibers. Dystrophin is part of the dystrophin-glycoprotein complex (DGC), which bridges the inner cytoskeleton (F-actin) and the extra-cellular matrix. [provided by RefSeq, Jul 2008]
Gene Sequence 5:
most common caused disease/description:This gene encodes a member of the fibrillin family. The encoded protein is a large, extracellular matrix glycoprotein that serve as a structural component of 10-12 nm calcium-binding microfibrils. These microfibrils provide force bearing structural support in elastic and nonelastic connective tissue throughout the body. Mutations in this gene are associated with Marfan syndrome, isolated ectopia lentis, autosomal dominant Weill-Marchesani syndrome, MASS syndrome, and Shprintzen-Goldberg craniosynostosis syndrome.

Feedback on last semester
What topics really confused you?
EVERYTHING
What topics do you feel very clear on?
CEllS
What lab/ activity was your favorite? Why?
THE KIMCHI, BECAUSE WE GOT TO MAKE IT.
What lab/activity was your least favorite? Why?
I DON'T REMEMBER.
If you could change something about the class to make it better, for instance the type of homework (not the amount) what would it be and why?
THE BLOGS BECAUSE THEY'RE CONFUSING
