1.Place the following in order from largest to smallest:
1. nitrogenous base
2. chromosome
3. nucleus
4. gene
5. nucleotide
2.Plasmids used for recombinant DNA work typically contain a gene for resistance to some type of antibiotic. The reason for this:
a.Helps you select out bacterial cells that have taken up the plasmid by
incubating them in the presence of the antibiotic
b.Helps make sure your culture doesnât get contaminated with viruses or fungi
c.Helps protect biotechnology lab workers from becoming infected with the bacteria
d.Helps make new types of antibiotic-resistant bacteria that will causewidespread disease and give the biotechnology industry new drugs to manufacture
3.Put these events in the correct sequence:
1-translation
2-mRNA splicing
3-transcription
4.A human protein product requires modifications in the endoplasmic reticulum and Golgi. Which of the following is true?
a.Bacteria will be able to produce this product, since they contain an endoplasmic reticulum and Golgi.
b.Bacteria will not be able to produce this product properly, because they lack an endoplasmic reticulum and Golgi.
c.This product should be produced in a virus, which is the least expensiveeukaryote that can be grown.
d.No cell type can produce this protein, so the company needs to move on to a different product.
