Genetic Engineering with the Amoeba Sisters

What was the outcome when bacteria were given a gene from a bioluminescent jellyfish?

• They became resistant to antibiotics

• They started producing human insulin

• They developed the ability to glow under UV light

• They grew significantly larger

Which human hormone is commonly produced by genetically engineered bacteria in a lab setting to treat Type 1 diabetes?

• Adrenaline

• Estrogen

• Insulin

• Testosterone

What is a key advantage of using bacteria in genetic engineering for producing substances like insulin?

• They are complex eukaryotic organisms

• They grow and multiply at a slow rate

• They require a large amount of space

• They multiply quickly and are easy to grow

What is the term for the process where a cell, often bacteria, takes up DNA from its environment and incorporates it?

In the process of creating recombinant DNA, what is the primary function of restriction enzymes?

• To synthesize new DNA strands

• To join DNA fragments together

• To cut DNA at specific nucleotide sequences

• To replicate plasmids within the cell

In genetic engineering, what is the primary role of a vector?

• To cut DNA at specific sequences

• To transport recombinant DNA into an organism
