Practical Questions o the Day
If an atom is the basic unit of matter, what is the basic unit of life?
How did the cell get its name?
Cell the basic structural and functional unit of life
All living things
Permanent alterations in a normal DNA base sequence (that were never corrected)
Point mutation A single-base mistake is made in a sequence
Through replication and cell division, mistakes get passed on forever
Why is inbreeding usually a bad idea?
Are females or males more likely to be colorblind?
What causes Down syndrome and other genetic disorders?
Many human disorders have a genetic basis
Humans have 23 pairs of chromosomes
Not all traits are dominant/recessive
Sometimes traits appear to blend
Blending is not happening!
Red (R) gene is code for a red pigment
White gene (r) is code for no pigment
RR= red pigment
Rr= as much

What are chromosomes and why do they matter?
What are genes and why should I care?
Major characteristic of living things: ability to grow and reproduce
Most organisms can repair damaged tissue
Many traits are inherite
What are mitosis and meiosis and should I really care?
What is cancer and why is a cure so elusive

A repeating pattern of growth and function, DNA copying, and cell division

I. Human Genome Project
-Identify all the approximate 30,000 genes in human DNA.
-Determine the sequences of the 3 billion base pairs that make up human DNA.
-Store this information in da
