Would appreciate some help!
Which one of the following is the biggest challenge that must be overcome in order to get a bacterium like E. coli to make a human protein:
A The genetic code is different in humans than it is in bacteria.
B Bacteria can’t splice out introns
C The vector is often antibiotic resistant
D Bacterial promoters are palindromes
E It is impossible for bacteria to make human proteins
