An amino acid is synthesized by the prokaryote, e coli. the genes for the enzymes responsible for synthesizing this amino acid are encoded in an operon. the operon is regulated by a repressor. when the amino acid binds to the repressor, the repressor changes shape so it can bind to the operator. which of the following statements is true? a. when levels of the amino acid are high, it binds to the repressor, allowing synthesis of this amino acid to proceed. b. when levels of the amino acid are low, it binds to the repressor, allowing synthesis of this amino acid to proceed c. when levels of the amino acid are high they bind to the repressor ending the synthesis of this amino acid. d. when levels of the amino acid are low they bind to the repressor ending the synthesis of this amino acid.

The united states produces an average of 429 billion pounds of food annually. about 133 billion pounds of that food ends up as waste.the percentage of food that the united states wastes each year is %.

Taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? view available hint(s)taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? the enzyme will not work on human dna.nothing should be altered.the ph should be decreased.the temperature should be raised.
