What is the function of DNA?
Sugar
PhosphateNitrogen Bases
Fill in the base pairs. Remember your base pair rules.
Label: -Sugar-phosphate backbone-Base-Hydrogen bonds
Fun Facts
If you wrote down all of the bases in one cell, you would fill a stack of 1,000 phone books with A's, T's, G's and C's
Fun FactsIf you unraveled all your chromosomes from all of your cells and laid out the DNA end to end, the strands would stretch from the Earth to the Moon about 6,000 times.
