Genetic Technology

Thursday April 11^th

Even though each body cell in an individual contains the same DNA, the functions of muscle cells and liver cells are NOT the same because….

A.  Mutations usually occur in genes when muscle cells divide

B.  Liver tissue develops before muscle tissue

C.  Liver cells produce more oxygen than muscle cells

D.  Liver cells use different genes than muscle cells.

Even though identical twins have the same genetic material, they may develop slightly different characteristics because

A.  Each twin receives different chromosomes from the egg

B.  One twin may only have genes from the father

C.  Gene expression may be influenced by factors that switch genes on and off

D.  A gene mutation may have occurred before the zygote divided

Today we started into different genetic technologies such as DNA fingerprinting, cloning and transgenic organisms.  The next couple days is going to be a lot of discussion and looking at specific examples.  You will not be writing NOTES on this  (YAY for you guys haha) but you will be following along with the reading and we will continue to use different video clips and news articles to supplement this chapter. 

Here are a couple of the videos we watched and some of the slides we had that sparked some VERY interesting discussions (Especially about human cloning!)
