Back

Pectinase

Front

This is the practice of inserting the DNA of another species into an organism's DNA so that the organism gains a new trait. (1m)

Back

Genetic Engineering

Front

Why did scientists edit the genes of bacteria to produce insulin?

Back

Because bacteria have simple DNA that is easier to manipulate, making it easy to produce insulin in a lab
