“E. coli can be considered a manufacturing unit in the field of genetic engineering.”
Explain this statement.
A. The recombinant DNA produced by the combination of an E. coli DNA and the gene of interest are inside the donor organism’s body, where it is multiplied and expressed into its protein product.
B. The recombinant DNA produced by the combination of a vector and the gene of interest are inserted in the E. coli, which produces multiple copies of this recombinant DNA along with the chromosomal DNA and expresses the gene.
C. The recombinant D

Question

“E. coli can be considered a manufacturing unit in the field of genetic engineering.”
Explain this statement. 
A. The recombinant DNA produced by the combination of an E. coli DNA and the gene of interest are inside the donor organism’s body, where it is multiplied and expressed into its protein product.
B. The recombinant DNA produced by the combination of a vector and the gene of interest are inserted in the E. coli, which produces multiple copies of this recombinant DNA along with the chromosomal DNA and expresses the gene.
C. The recombinant D

anonymous · Answer

The correct answer is B. 

A is not true, because the E. coli is grown outside a donor body. It is just grown in the lab. 
C is not true, because the E. coli DNA is already in the bacterium.
