Title: The invasion of bacteria into the roots of legumes is facilitated by a long complex polysaccharide'


1
The invasion of bacteria into the roots of
legumes is facilitated by a long complex
polysaccharide.
2
The invasion of bacteria into the roots of
legumes is facilitated by a long complex
polysaccharide. In this case, the bacteria has
been labeled with GFP.
3
The invasion of bacteria into the roots of
legumes is facilitated by a long complex
polysaccharide.

7
The central dogma of biology DNA is transcribed
into RNA which is then translated into
protein. Slide provided by Tom Cech
8
RNA may have structure, too. Base-pairing may
occur between the nitrogenous bases of a single
RNA strand. A single strand of RNA folds into
complex structure.
9
The backbone of a polypeptide may fold up into an
alpha-helical structure. The helix is held
together by hydrogen bonding of the polypeptide
backbone. The R groups or side chains of the
amino acids are not shown in this
movie. http//www.bmb.psu.edu/faculty/tan/lab/mov

11
The backbone of a polypeptide may fold up into a
beta sheet structure. The amino acids in sheets
are found in extende or stretched-out
conformations. The sheet is held together by
hydrogen bonding of the polypeptide backbone.
The R groups or side chains of the amino acids
stick in and out of the sheet. http//www.bmb.psu

Proteins are made of any number of combinations
of beta sheets and alpha helices. This is the
C-terminal domain of BRCT, a protein involved in
breast cancer. http//emboj.oupjournals.org/cgi/c

Proteins are made of any number of combinations
of beta sheets and alpha helices. This is the
TAQ MutS-DNA complex. This protein is involved
in DNA mismatch repair. W Yang, P. Hsieh. Nature

14
Proteins are made of any number of combinations
of beta sheets and alpha helices. This protein
is an oncogene known as Ras. Oncogenes are
involved in the development of cancer. http//www

Bizarre Toes
Geckos are capable of sticking to and climbing
steep surfaces by utilizing Van der Waals forces
between hairs on their toes and the
surface. Slide courtesy of Bob Full

The Gecko sequence Student Response That
gecko thing was pretty sweet! (I learned) that
van der waals forces can be strong enough to
allow a gecko to stick to the wall. I thought
they would be much weaker, but I guess in large
amounts they can be that strong.
22
The cores or insides of many proteins are often
made of many hydrophobic residues coming together
and forming a hydrophobic core. http//btcpxx.che
