Question

If source DNA is extracted from a eukaryotic organism and used to create transgenic bacteria, why will the mRNA transcribed from the recombinant DNA encode a defective protein in the bacteria?

a) The bacteria lack the necessary ribosomes for protein synthesis
b) Eukaryotic DNA cannot be transcribed in prokaryotic organisms
c) The bacterial RNA polymerase cannot process eukaryotic mRNA
d) The bacterial codon usage and post-translational modifications differ from eukaryotes

Answer 1

The mRNA transcribed from the recombinant DNA will encode a defective protein in the bacteria due to differences in gene expression and protein synthesis between eukaryotes and bacteria.

Step-by-step explanation:

The mRNA transcribed from the recombinant DNA will encode a defective protein in the bacteria because of the differences between eukaryotes and bacteria in terms of gene expression and protein synthesis. Bacterial RNA polymerase cannot process eukaryotic mRNA properly because they have different promoters and RNA polymerases. Additionally, the codon usage and post-translational modifications differ between eukaryotes and bacteria, leading to the production of a defective protein in the bacteria.
