Scientists have noticed that the entire DNA molecule has the same width, despite the fact that the four nucleotides are not the same width. Now that you've created a model, explain how this makes sense (hint: it has something to do with the number of rings for each nitrogenous base).

sex cells are usually half's then they find another half and make a fertilize egg

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
