DNA for Dinner Lesson 5: From Bread to Biotech

Learn how yeast uses sugar to make holes in your loaf of bread.

See how male and female corn cells come together to form the grain on an ear of corn.

Create a recombinant story using cutting and pasting methods similar to those used for DNA manipulation.

Find out how PCR can be used to multiply gene fragments.

Literally biotechnology means using organisms to do a job, like using yeast to make bread.

Modern biotechnology uses new genetic tools to modify genomes and speed crop development.

In the past humans modified genomes by crossing plants with different traits and selecting ones with improved traits.

A part of modern biotechnology, called genetic engineering, involves isolating genes, linking them to on and off switches and introducing them into the same or different organisms.

Special enzymes are used to cut (restriction enzymes) and paste (ligase) DNA, in a process called recombinant DNA.
