Question

In textbooks pictures of DNA look real colorful, showing the sugars, phosphate groups and nitrogen bases. How does "real" DNA differ from these drawings????

Answer 1

it won't look like that at all because in our cells the DNA will be bound by many molecules or water, salts and other compounds. not only that, if you look at the structure of DNA with the atoms represented as their real size (aka space fill model) it won't look like the nice ball and stick models in most textbooks but more like a slightly twisted and oversized sausage

Answer 2

As far as the structure and the shape it's the same but as for the colors they're colorful really but in the book it uses more colors so that everything can be identified by the students.

Answer 3

uhh not much, the dr awings are pretty much on the dot

of course they might not be as colorful as that, i think they use the color to mostly show you which structure is which

Answer 4

The actual colors of molecules are pretty drab when you get down to the tiny groups of amino acids. They use any old color to show contrast. Since you can't see these things without an electron microscope, there is no color to the system anyhow . You tell the computer what color you want groups with certain characterists to be and all of them will be that same color. The camera on planet exploratory satalites sees in one or two coloros and they use the computer to make the pictures whatever color they want to for contrast.
