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?
Transgenic organisms have had a gene or genes from another species inserted into their
genome. 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.
