Leon Jin, you mentioned on "armoured sea robin". How about doing a short write-up on it to share with everybody? You can include pictures too! You can email to us (email address below) and we'll post it up for you.


Chelsea, regarding your question, the diameter of the DNA helix is about 2 nm and the vertical rise per base pair is 0.34 nm.

How small is 1 nm? (Note: nm is nanometer, similar to cm as centimeter)

1 nm = 0.000000001 m

So have you got an idea on the size?
