FINAL JEOPARDY!
DNA Function for 200
During DNA replication, a template strand reads
TTTAGCTAGCTA.
What is the sequence of the new strand?
AAATCGATCGAT
DNA Function for 400
What sequence of mRNA makes up the
start codon? What is the anticodon of
the corresponding tRNA?
AUG
UAC
DNA Function for 600
When translation is complete, what might
immediately happen to the…
mRNA = translated again by another ribosome to
make additional copies of the resulting protein
Polypeptide = will be shaped into a functional
protein
tRNA = will pick up another matching amino acid
and bring it to another ribosome
DNA Tech for 200
What is the specific original purpose of
restriction enzymes?
They are produced by bacteria to destroy
the DNA of invading viruses
DNA Tech for 400
What is the major functional difference between
adult stem cells and embryonic stem cells?
ASCs are pluripotent. They can divide to produce
a few different types of somatic cells.
ESCs are totipotent. They can divide to produce
any cell in the body (or a whole new embryo).
DNA Tech for 600
What is the purpose of heating a sample in
the process of PCR?
It denatures the DNA which means that the
hydrogen bonds holding together
complementary bases of opposite strands
break. This separates the strands.
Potpourri for 200
How many unique nucleotide variations
exist in our cells?
8
4 DNA nucleotides with A, C, G, or T
4 RNA nucleotides with A, C, G, or U
Potpourri for 400
What is transformation, and why is it an important
step in gene cloning?
It is the absorption of foreign plasmid DNA into
bacterial cells.
Once the plasmid is absorbed, the bacteria can
express the new genes, and they copy the whole
plasmid whenever they carry out binary fission.
Potpourri for 600
How is it that a mutation might occur in the DNA, but there
is no corresponding change in the organism’s phenotype?
1)
2)
The mutation may not be within a gene.
The mutation may be transcribed into a different mRNA
codon, but it may still code for the same amino acid.
