Which headline would be an example of genetic engineering? a.) mrs. o'hara gives birth to fourth redhead b.)farmer brown's pigs: best quality ham for the money c.) gene added to liver improves clotting time d.) bacteria make human insulin

The correct answer is option D, Bacteria Make Human Insulin

Explanation:

Through the recombinant technology of genetic engineering, DNA of one organism can be transferred into the DNA of other organism. In a bacteria, the genes can be modified to produce human insulin. The gene for human insulin is chemically joined to the plasmid of bacterial DNA. Thus whenever the bacteria replicates its DNA, it also replicates the gene for human insulin thereby producing multiple sets of synthetic human insulin.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
