(can/cannot) be used over and over
again, reduces (reduces/increases) the
activation energy, and only fit with one
(one/many) type(s) of substrate.

Station 9:
Fill in the blanks below.
Mitosis is the process of creating 2
identical NUCLEI (nuclei/cells).
Cytokinesis is the process of creating 2
identical CELLS (nuclei/cells).
Station 10:
What is a change or a mistake in the DNA?
MUTATION
The two types of mutations are
POINT MUTATION = 1 change
(substitution)
FRAMESHIFT MUTATION = more than 1
change (addition or deletion)

Gly – Asp – His - Asp
Which mRNA strand had the biggest
mutation? 3
Station 12:

one original parent cell. If the parent cell has 26
chromosomes, how many chromosomes do each
daughter cell have? 26
Parent Cell
Daughter Cells
26

In 1917 the biologist Thomas Hunt Morgan conducted
studies in which he kept some caterpillars in the dark and
placed other under red, green, or blue lights. Exposure to
red light produced butterflies with brightly colored wings.
Exposure to green light resulted in dark-colored wins.
Exposure to blue light or no light resulted in pale-colored
wings. What was the most likely conclusion of Morgan’s
research?
a) The pigment in butterfly wings absorbs light from the
environment
b) The phenotypic expression of wing shape depends on
color pigmentation in butterflies.
c) The genes regulating wing color in butterflies are
influenced by environmental factors.
d) Caterpillars exposed to red and green light are healthier
than caterpillars exposed to no light or blue light.
Hemoglobin is a protein that carries oxygen in red
blood cells. The hemoglobin molecules produced by
some people have one specific amino acid that is
different from the amino acid at that position in
normal hemoglobin. Which is the most likely cause?
a) the hemoglobin gene contains a mutation
b) an error occurs during the folding of the hemoglobin
protein
c) enzymes replace the amino acid once the hemoglobin
is produced
d) an error occurred during the M phase of the cell cycle
The mold Aspergillus flavus grows on grain. A. flavus
produces a toxin that binds to DNA in the bodies of
animals that eat the grain. The binding of the toxin
to DNA blacks the process of transcription, so it
directly interferes with the animal’s ability to do
which of the following?
a) Transport glucose across the cell membrane
b) Produce ATP using energy released from glucose
c) Transfer proteins from the endoplasmic reticulum
to the Golgi complex
d) Send mRNA from the nucleus to the ribosomes
