different things. Why don't our yourselves make the same proteins
to do the same things?

differentiated due to differences in gene expression.

essay question: 1.explain why all cells must have the four parts
all cells have.
2. Be able to compare and contrast prokaryotic and eukaryotic
cellular characteristics. (including DNA location, cell wall
makeup)
Which of the following is a difficulty in getting
prokaryotic cells to express eukaryotic genes?
a. The signals that control gene expression are different for
prokaryotes, thus requiring prokaryotic promoter regions to be
added to the vector.
b. The genetic code differs because prokaryotes substitute the base
uracil for thymine.
c. Prokaryotic cells do not recognize eukaryotic stop and start
codons.
d. The ribosomes of prokaryotes are not large enough to handle long
eukaryotic genes.
1.
a Explain why all cells in an organism
are genetically equivalent, but may vary in phenotype.
b) Explain why the
same genotype does not always produce the same phenotype and why
the same phenotype can be the result of different genotypes.
c) For a cell that is right after DNA
replication, where 2n=6. How many molecules of DNA are there?
d) How many chromosomes are there?
e) How many homologous pairs are there? How many unique
chromosomes are there?...
