2. Be able to apply the information.
Lecture is presented linearly, but applying the information may mean seeing it non-linearly.

Have GMO's been beneficial, and what are the risks?
We have genetically modified both plants and domesticated animals...What about humans?

Using viruses to add genes to humans
As with computer technology, the plunging cost of DNA sequencing has opened new applications in science and medicine.Graph: ADAPTED FROM GRAPH PROVIDED BY JEFFREY SCHLOSS/NHGRIGENE SEQUENCING: The Race for the $1000 Genome (17 March 2006) R Service Science 311:1544 - 1546
The material cost will soon be ~$1,000 to sequence a complete human genome at a consumer cost of ~$5,000http://www.nature.com/news/2008/081006/full/news.2008.1151.html
How close are we to picking our offspring?
Karyomapping is a new technique developed at a British fertility clinic can test for 15,000 known genetic disorders. It takes DNA from 8-day-old in vitro fertilized embryos as well as from the parents and possibly other relatives.The test costs ~$2,300.

How close are we to picking our offspring?
“…the test could also be used, more controversially, to detect a genetic profile which showed a susceptibility to conditions such as heart disease or cancer.”

When does picking the ‘best’ become choosing traits?
Sex ratio in China, est. 2008
at birth: 1.11 male(s)/femaleunder 15 years: 1.13 male(s)/female15-64 years: 1.06 male(s)/female
Compare to U.S. at birth 1.05 male(s)/femalehttp://www.indexmundi.com/china/demographics_profile.html
When does picking the ‘best’ become choosing traits?
What ‘abnormality’ might a parent choose?
One study found that each inch above average may be worth $789 more in salary per year.

One important consideration of structure and function…surface area

Why is surface area so critical?
Animals (and plants) must exchange various components with the environment

Organisms are organized:
atoms
molecules
organelles
cells
tissues
organs

Four major tissue types in animals:
epithelial, connective, muscle, and nervous

Fig 40.5
Epithelieal tissue:Covers and lines body and/or parts. Tightly packed cells.
Connective tissue:Holds and supports. Few cells with an extensive extracellular matrix.

Fig 40.5Muscle tissue:Movement. Long muscle fibers cells.
Nerve tissue:Signaling. Generally long cells, neurons.
