7. How are haploid cells different from diploid cells?




8.

Mitosis produces [ haploid / diploid ] cells.


Meiosis produces [ haploid / diploid ] cells.


9.

DNA Sequence:


CCG

AAT

GGA

CAT


mRNA sequence?

___

___

___

___


amino acids?


___

___

___

___


10.

What would happen to the amino acid sequence if there was a mutation in the
DNA?





11.

Describe the
structure & function of


a) mRNA



b) tRNA



c) rRNA


12
.

Label the illustration below.





















13.

In seals, the gene for long
whiskers is dominant (W) and the gene for short
whiskers is recessive (w).


a)

What percentage of offspring would be expected to have short whiskers from a
cross of two long
-
whiskered seas


one that is homozygous dominant and one
that is heterozygous?





b)

If one parent seal is pure long
-
whiskered and the other is short
-
whiskered,
what percent of offspring would have short whiskers?




c)

If two long
-
whiskered seals suddenly had a short
-
whiskered baby, what could
be concluded about the genotype of the pa
rents?




Label:

DNA

mRNA

tRNA

ribosome

polypeptide sequence

nuclear membrane

amino acid

transcription

translation


d) Suppose there was a long
-
whiskered seal, but the zookeepers didn’t know
whether it was a homozygous (pure) seal or a heterozygous (hybrid) seal.
This
seal should be crossed with
what kind

of seal? What will their offspring tell
you about t
he genotype of the seal?





e) Elephants can have long tusks, short tusks, or medium
-
length tusks. The gene
for long tusks (L) is incompletely dominant, as is the gene for short tusks (S).
What is the genotype that codes for a medium
-
length tusk?



f
)

What would be the genotype and phenotype frequency of offspring between
two elephants with medium
-
length tusks? Draw a Punnett square to support
your response.





14.

What is the process illustrated in this
diagram? Label any cells that are diploid
and
any cells that are haploid. If these were
human cells, what would be the diploid
number? (2n = __)











14.

What are the symptoms of these genetic disorders?


a) colorblindness


b) hemophilia


c) sickle cell anemia


d) Down’s syndrome


15.

What is this molecule?

What is the structure that is labeled X on this
diagram?
















16.

What do the letters A, T, G,
and C

refer to?

In which molecule will you find
them?





17. If you know the percentage of adenine in a DNA molecule,

how would you
determine the amount of cytosine in that same molecule?
