Water for 100 What is it about O-H bonds in water makes it a
polar molecule? Oxygen has a greater attraction for electrons, so
the electrons spend more time around the oxygen atom. This causes
it to develop a partial negative charge while the hydrogens are
partially positive.
Slide 4
Water for 200 What is the significance of waters high specific
heat? It takes more energy to change the temperature of water.
Slide 5
Water for 300 In what important chemical pathway is water a
reactant? Hydrolysis (or photosynthesis)
Slide 6
MacMole for 100 What are the 4 classes of macromolecules?
Carbohydrate, Lipid, Nucleic Acid, Protein
Slide 7
MacMole for 200 What are three differences between DNA and RNA?
DNA Double-stranded, deoxyribose, and thymine RNA Single-stranded,
ribose, and uracil.
Slide 8
MacMole for 300 What happens in each of the 4 levels of protein
structure? 1) Sequence of amino acids formed by peptide bonds. 2)
Coiling and sheet formation via hydrogen bonds. 3) Folding via
hydrogen bonds, ionic bonds, disulfide bridges, and hydrophobic
interactions. 4) Aggregation of separate polypeptides.
Slide 9
Enzymes for 100 What part of an enzyme makes direct contact
with a substrate? Active site
Slide 10
Enzymes for 200 Why might the rate of reaction of an enzyme
stay constant despite an increase in substrate concentration? This
will happen if the enzyme is saturated.
Slide 11
Enzymes for 300
Slide 12
Organelles for 100 What organelle would be found in unusually
large amounts in leaf cells? Chloroplasts
Slide 13
Organelles for 200 Why are mitochondria believed to have once
been independent organisms? Double membrane, circular DNA, binary
fission, ribosomes
Slide 14
Organelles for 300 To what organelle will a signal recognition
particle lead? Rough endoplasmic reticulum
Slide 15
Transport for 100 What is an electrochemical gradient? A
difference in the concentration of charged particles (ions) across
a membrane.
Slide 16
Transport for 200 How can some wall-less unicellular organisms
alleviate conditions that arise in hypotonic environments?
Contractile vacuole
Slide 17
Transport for 300 O 2 moving from the high concentration of
capillaries to the low concentration in the interstitial fluid is
an example of ____? Diffusion (a type of passive transport)

Slide 19
Technology for 200 What are the three steps of PCR, and what
are the temperatures at which they act? ~95CDenaturation
~55CPriming ~72CElongation (addition of nucleotides)
Slide 20
Technology for 400 How can one isolate a desired DNA fragment
from a mixture of fragments? Electrophoresis
Slide 21
Technology for 600 What does RFLP stand for, and why are they
suitable candidates for use in DNA fingerprinting? Restriction
fragment length polymorphism. They have lots of variation so we can
better distinguish between individuals.
Slide 22
Division for 200 What checkpoint prevents nondisjunction? The M
checkpoint between metaphase and anaphase.
Slide 23
Division for 400 Use chiasmata, recombinant, synapsis, and
tetrads correctly in a sentence that demonstrates their
relationship. Recombinant chromosomes can result from the chiasmata
that form within tetrads during synapsis.
Slide 24
Division for 600 A person has the same type of cancer that has
been in the family for generations. How can susceptibility to
cancer be inherited? Mutations to tumor suppressor genes or proto-
oncogenes can be passed down from generation to generation.
Slide 25
Genetics for 200 AABbCcDD x AaBbCCDd What proportion of
offspring would you expect to be homozygous dominant for all genes?
x x x = 1/32
Slide 26
Genetics for 400 To what end of an existing strand may DNA
polymerase add new nucleotides, and what is the result of this
limitation on the lagging strand? The 3 end. Okazaki
fragments.
Slide 27
Genetics for 600 What type of mutation will ALWAYS result in a
shorter polypeptide chain being produced? Nonsense
Slide 28
More Gen. for 200 Four bacterial cells, 20-minute generation
time, three-hour duration. 4 x 2 9 = 2048
Slide 29
More Gen. for 400 What are two ways gene expression can be
stopped? Coiling of DNA (heterochromatin) Methylation RNA
degradation Translation blockage Protein degradation
Slide 30
More Gen. for 600 What two types of genes help to regulate the
cell cycle? Tumor suppressor genes and proto-oncogenes
