What is the difference between a rock and a plant?
Living things are able to arrange atoms from simple to complex
combinations, that is, they can make entropy go backwards.
Living things can transmit traits to new cells and organisms
(each trait is ultimately the ability to mediate a particular
rearrangement of atoms).
” deals with transmission of traits
” deals with attempts to manipulate
this transmission for useful purposes:
medicine (diagnosis, treatment)
clean-up and analysis of pollutants
includes “recombinant DNA
” and “genetic
” as well as conventional techniques
Its understanding requires understanding genetics (genetics is
important and interesting in its own right).
at molecular and cellular levels: DNA and its expression;
how “genetic material
” or “genes
” (ie, DNA) are
transmitted from generation to generation; how
expression of gene(s) produces identifiable trait(s)
at organism and population levels: diversity and
evolution of life on Earth
We must understand these things (particularly at the
molecular and cellular levels) before genetic technology
makes sense; this will take much of this course, but the
hope is that it will allow appreciation and analysis of
