What are transgenic organisms? Explain the rationale behind using these organisms to produce some
of the proteins needed for human use, instead of relying solely on proteins produced by genetically
engineered E. coli What will be an ideal response?
Concepts to Consider: Differences in prokaryotic and eukaryotic gene regulation, post-transcriptional
processing, and post-translational processing; these factors contribute to low yields and/or additional
processing may be required to generate a functional protein. Transgenic eukaryotes would have the
same regulatory mechanisms and would therefore be able to produce a functional protein product from
an inserted or foreign gene
