Answer: C
Explanation:
For example, in trp-operon, an abundance of tryptophan. coli inhibits the expression trp-operon genes.

trpR gene is expressed continually at a low level
we would loose the capability of curing every simple sickness that antibiotics can cure and will eventually die from sickness and disease
Green, like grass and trees...?
<span>One important area of DNA research is that of genetics and medical research. Due to our discovery of DNA, our ability to actually diagnose diseases early on has been vastly improved. In addition, we have been able to better assess a person's genetic susceptibility to specific diseases. In doing so, we have also paved the pathway to formulate brand new drugs to treat these diseases. In fact, drugs can essentially be custom made to complement a person's personal biochemistry and genetic makeup. For those diseases that were previously considered lethal and where treatment was either non-existent or largely unsuccessful, the discovery of DNA has essentially led to breakthrough drugs and treatments for patients with serious illnesses.</span>
