Human growth hormone (HGH) is a peptide hormone that stimulates growth, cell division and regeneration. HGH is made in the anterior pituitary gland. A researcher wants to introduce the gene encoding human growth hormone into E. coli so she can produce large quantities of the peptide hormone for medical treatments. What strategy should the researcher take?
A. Obtain the HGH gene from a human anterior pituitary gland cDNA library.
B. Obtain an HGH gene from another prokaryote.
C. Obtain the HGH gene from a human genomic library produced from DNA of the anterior pituitary gland.
D. Obtain the HGH gene from a human genomic library produced from DNA from any human tissue.
E. Obtain an HGH gene from either a genomic or cDNA library.
A. Obtain the HGH gene from a human anterior pituitary gland cDNA library.
