Describe how protein/DNA interactions occur. How does a protein
bind to DNA? Are there different types of DNA binding proteins? Can
they be specific to a sequence in the DNA?
2. Protein-DNA binding
a) List the types of interactions that are involved between a
protein that binds DNA non-specifically and DNA.
b) List two proteins that bind to DNA non-specifically.
c) List the types of interactions usually involved between a
sequence-specific DNA binding protein and DNA.
d) List two proteins that bind DNA specifically.
e) What is the difference between non-specific and specific
protein binding to DNA?
Describe the positive and negative interactions that occur
between different species groups in a community. How does predation
differ from herbivory and parasitism? How do you think mutualism
evolves between two species and describe how mutualism affects you
on a personal basis day to day.
Short answer: 1-Describe several different types of mutualistic
interactions that can occur among organisms, providing specific
examples and the benefits I each organism gains from the
interaction.
2- List, describe and give the purpose for three types of
migrations from one habitat (environment) to another, and give
examples of organisms that exhibit these types of migrations.
Describe how spontaneous point mutations occur in bacteria. How
may these types of mutation affect protein function? Explain the
function and importance of genetic variation in bacteria. Include
in your answer descriptions of two examples where genetic variation
has resulted in differences in the behaviour of different bacterial
strains of the same species.
How does Fluorouracil work, biologically
- What enzyme/protein does this drug bind to?
- What is the function of this enzyme/protein?
- Where is its active site?
- What is the substrate for the protein/enzyme?
- What is the Km and Vmax of this enzyme if this information is
available?
