How do proteins pack DNA into viruses? How do viruses invade cells?
Biophysics discovers how atoms are arranged to work in DNA and proteins. Protein molecules perform the body’s chemical reactions. They push and pull in the muscles that move your limbs. Proteins make the parts of your eyes, ears, nose, and skin that sense your environment. They turn food into energy and light into vision. They are your immunity to illness. Proteins repair what is broken inside of cells, and regulate growth. They fire the electrical signals in your brain. They read the DNA blueprints in your body and copy the DNA for future generations. Biophysicists are discovering how proteins work. These mysteries are solved part by part. To learn how a car works, you first need to know how the parts fit together. Now, thanks to biophysics, we know exactly where the thousands of atoms are located in more than 50,000 different proteins. Each year, over a million scientists and students from all over the world, from physicists to medical practitioners, use these protein structures for
