atoms and cells etc in the body

[mollykins]

You know when you see a picture of the structure of dna like this; http://www-tc.pbs.org...-coll-dna-knoll-l.jpg is each little ball an atom? if not what are they and how do they compare to atoms?

And how many atoms make up a piece of dna?

And how many atoms make up a cell?

And roughly how amny cells in the body?

And finally how many atoms in the human body would that make?

Yes in this image they are atoms. Each different colour is a different element.

The second illustration on the wikipedia page shows the structure of atoms with names and it looks similar to the diagram. Sometimes thes models are done at the scale of nucleotides.

This isn't homework and won't be on the exam i was curious but couldn't find an explanation so i turned to the fine people of answerbank.

Oh I see. Well
good luck. Hope you've decided what food to take. I would recommend a banana. Slow energy release you see. I wonder how many atoms there are in a Banana?

For breakfast; poridge, and raisins. Lunch; tinned macaroni cheese followed by dried apricots etc and a chocolate bar. Tea; cuppa soup, crackers and a little bit more choccy. With fruit, nuts and sweets inbetween.

I might take coffee granules and that coffee mate powdered milk stuff or hot chocolate aswell.
