If a woman holds a
heterozygous
genotype for dimples,
what alleles will be in
her egg cells?
5 - $400
Answer
Half of her eggs would carry the
dominant allele, while the
other half carry the recessive
allele.

If Joey’s parents both
don’t have a trait but
Joey has it, explain
how this is possible.
5- $600
Answer
Both of Joey’s parent have the
heterozygous genotype for
that trait. They are both
carriers of the recessive allele
and therefore Joey received
both recessive traits, one
from each parent.

Mary has a recessive
genetic disease and her
husband is healthy. What
are the chances that their
children will have the
disease?
5 - $800
Answer
It depends what Mary’s
husband’s (the father’s)
alleles are.

What determines the
order of the amino
acids when creating a
protein?
6 - $100
Answer
The order of the amino acids is
determined by the order of
the bases along the mRNA.
(Three bases = amino acid)

Answer
Messenger RNA (mRNA)

synthesis, what is structure B and
what is it’s function?
6 - $400
Answer
B is the Ribosome which makes
the proteins
6 - $600
What is structure D?
6 - $600
Answer
D is the Transfer RNA (tRNA)
6- $800
What is structure C and how
does it relate to structure A?
6 - $800
Answer
C is an Amino Acid. The amino
acids combined to form a protein
chain, which is structure A.
7 - $100
What is structure E and
what is it’s function?
7- $100
Answer
E is the Messenger RNA (mRNA) and it
copies the DNA, brings it to the
cytoplasm, where a ribosome attaches to
it and makes the protein.

D and P are what hold
the nitrogen bases
together to form DNA.
