This press release contains a glossary and pointers to background materials for Dr. Rogan's and Dr. Schneider's presentations. See http://www-lecb.ncifcrf.gov// for more information.
Information theory: a mathematical theory of symbols and states and how they can be made distinct in the presence of noise. It was invented by Claude Shannon in 1948. A primer on the topic is available from http://schneider.ncifcrf.gov/paper/primer/index.html
Molecular biology: the study of living systems at the molecular level.
Molecular information theory: the study of living
systems at the molecular level by using information theory.
Sequence logo: a graphical representation of the patterns at a set of
genetic binding sites. The human donor splice junction sequence logo is
shown here. See
http://schneider.ncifcrf.gov/sequencelogo.html for more examples.
Sequence walker: a graphical representation of a
single genetic binding site. The example given here shows the effect of a
mutation that causes blindness, found by R. Allikmets and M. Dean. See
Gumball machines: represent the packing of spheres in
a high dimensional space. In communications theory, the number of distinct
messages that can be sent over a communications channel depends on the power,
the interfering noise and the bandwidth used. This channel capacity can be
determined by counting the number of possible messages. Each gumball
represents a different message, and their relative positions is the coding.
In molecular information theory, each gumball represents a different state of
a molecule. See
