Chapter 20UNIT 30 C PERFORMANCE TASK
Investigating Human Traits
In this Performance Task, you will use the skills you gained
in this Unit to design and carry out a correlational study on
human traits to determine if they are autosomal or sex-
linked. Go to the Unit 30 C Performance Task link on the
Nelson web site to complete the task.http://www.science.nelson.com GOCracking the Code of Life
In this NOVAvideo, follow corporate and academic scientists as
they race to capture one of the biggest prizes in scientific
history: the complete, letter-by-letter sequence of genetic
information that defines human life—the human genome.http://www.science.nelson.com GO+ EXTENSION
Artificial Life
Scientists can now synthesize strands of DNA with any
nucleotide sequence they want. Does this mean that they can
create artificial life from these blueprints? Some scientists
believe the answer is yes, and that it isn’t that far away! Find out
why by watching this NOVAvideo.http://www.science.nelson.com GO+ EXTENSION
Golden Rice or Frankenfood?
Vitamin A deficiency is a leading cause of preventable
blindness. Scientists have developed a genetically-modified rice
that contains β-carotene, the precursor to vitamin A. Some see
this new rice as an important contribution to world health, but
others warn that genetically modified foods could have hidden
dangers. What do you think?http://www.science.nelson.com GO+ EXTENSION

Dr. Vanessa Auld, Quirks and Quarks genetics columnist
explains the details behind the discovery by a group of
American and Czech researchers of proteins that act like
small motors inside the nucleus of the cell. This discovery
is changing our understanding of how DNA is used to
manufacture the proteins and chemicals the cell uses to
sustain life.
