Scientists have engineered bacteria to produce human proteins such as insulin to treat diabetes suppose the unmodified eukaryotic gene coding for insulin is inserted directly into a bacterial chromosome. select the reasons why no expression would be seen in the bacterial cell for the insulin gene.
a. the bacterial rna polymerase will not bind to the eukaryotic promoter sequence.
b. the gene will induce attenuation in the bacterial cell, which will cause a delay in the transcription and translation of the insulin gene.
c. the bacterial nucleoid does not have the proper proteins to transcribe the eukaryotic gene.
d. bacteria cannot remove intronic sequence from a gene, so if the gene for insulin were transcribed, it would translate to a nonfunctional protein.

Single strand binding protein by peptide bond

Ithink the dna sequences may vary but the amino acid sequences are identical. 

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
