There are 25 major specialties in engineering that are recognized by professional societies. In any one of those 25 specialties‚ the goal of the engineer is the same. The goal is to be able to come up with a cost effective design that aids people in the tasks they face each day. Whether it be the coffee machine in the morning or the roads and highways we travel‚ or even the cars we travel in‚ it was all an idea that started with an engineer. Someone engineered each idea to make it the best solution

GENETIC ENGINEERING GENETIC ENGINEERING GENERAL STEPS What is Genetic Engineering? Genetic Engineering = inserting a foreign gene of interest into a host to transcribe and translate a particular protein. Ex. Inserting the human insulin gene into bacteria to mass produce it. General Steps Obtain the gene of interest (ex. insulin gene) Insert the gene into the host (ex. bacteria) Allow the host to multiply and express the foreign gene get your desired protein! Get lots of cells that can
