Question

How does genetic engineering make producing insulin easier compared to when insulin was produced through using a cow pancreas?

Answer 1

It reduces allergic reactions

Step-by-step explanation:

Insulin could be obtained from animals. This insulin is extracted from animals and then purified for use on humans.

However, genetically engineered insulin is produced by genetically modified bacteria. The advantage of this method of producing insulin is that it yields pure insulin with less allergic reactions in humans.
