7 Informationand Its Expressionin the Cell
7.3 The Expressionof BiologicalInformation
A Context for Understanding Gene Expression
When the organism expresses a set of genes,the result is the characteristics of that
organism. These characteristics are called its ____________.
The term “transcription” means the process of reading a base sequence in ____________ to
generate a complementary base sequence in ____________.
Why is the word “translation” used for protein production?
Information from DNA is transcribed into mRNA, which is then transported to ribosomes.
This phrase describes the role of ____________ in ____________ expression.
Describe 2 major problems that transcription solves for the cell.
Transcription: Using Some Genes Now and Some Not at All
In the process of transcription, the base sequence in the molecule ____________ is read by
the molecule ____________,an enzyme that makes RNA molecules.
Which RNA product helps the ribosome to recognize how and where to begin working?
Following the transcription event,list 4 separate parts of the overall processing of pre-
mRNA in the cell’s nucleus.
In the cell nucleus,a pre-mRNA has its introns removed by ____________ enzymes.
Translation: Making Proteins
In the translation process,tRNA molecules are also called “adapter” molecules. Why?
What is their function?
There are more than four kinds of amino acids in proteins. Each kind of amino acid must be
coded for in mRNA. Thus,a short sequence ofmRNA bases called a(n) ____________ is
used to code for each amino acid in the translation process.
What is a general name for a three-dimensional, folded molecule shaped like an “L,” with
an anticodon at one end and an amino acid attachment site at the other end?
Transferring correct amino acids to the ribosome during elongation is a good description of
the role of ____________ in the cell cytoplasm.
What is the role of tRNA synthetase in the cell’s cytoplasm?
Peptide bonds are formed during the ____________ stage oftranslation.
The role of the ribosome or its subunits:creating a channelfor ____________ to enterand
exit.
The role of the ribosome or its subunits:helping tRNA ____________-codons to bind to
mRNA ____________.
The role of the ribosome or its subunits:comparing ____________ anti-codons against
corresponding ____________ codons.
The role of the ribosome or its subunits:binding ____________ ____________ togetherto
form a polypeptide chain.
This sequence best represents the overall flow of ____________ in a cell: transcription,
pre-mRNA processing,translation, protein processing,export
List all of the organelles involved in the flow of information from archival DNA to its
expression as a resulting glycoprotein.

2. In order to elongate mRNA, RNA polymerase must unwind and open double-stranded
____________.
In order to elongate mRNA, RNA polymerase must sense correct ____________ and
incorporate them into the new RNA strand.
In order to elongate mRNA, RNA polymerase must dislodge the ____________ strand
from its temporary pairing with DNA.
In order to elongate mRNA, RNA polymerase must ____________ the RNA strand to
remove and replace copying errors.
The Genetic Code
The ____________ is often represented as a chart in which a specific sequence ofbases in
mRNA (a codon)is used to represent each amino acid building block found in the world of
proteins.
The genetic code is said to be degenerate. What does this mean?

8.1 A Thin Skin of Life Chasing Death
What are the 3 essential resources that a daughtercell must get from a parent cell or from
nature in order to succeed in living life?
Life perpetuates itself at the ____________ levelby acquiring monomers and energy
sources at the microscopic level and by carrying out absorption,processing and growing
“for” the organism.
8.2 Cell Division: A Requirement for Life
When DNA is replicated, the two strands are first separated through breakage of
____________; each strand then becomes a ____________ against which two new strands
are made.
8.3 Cell Division Is Part of a Cycle: The CellCycle
List the 4 symbols/names for the 4 stages ofthe cell cycle.
The “S” phase of the cell cycle represents the activity of DNA ____________.
Moving ahead with cell division is controlled by the interaction of hormones with cell
surface ____________ proteins,interaction of receptor proteins with ____________
intermediates, interaction of cyclins with ____________ proteins,and interaction of kinase
proteins with inactive ____________ proteins.
8.4 Mitosis
List in order the stages ofmitosis.
The nuclear membrane of the cell disintegrates during which mitotic period of the cell

result?
The de-condensation ofvisible chromosomes back into chromatin fibers is a defining
feature of which phase of the cell cycle?
8.6 Cancer:Mutation Threatening Design
The Unifying Basis of Cancer
