Goodbye to you my trusted friend. We've known each other since we were nine or ten. Together we've climbed hills and trees. Learned of love and ABC's. Skinned our hearts and skinned our knees. Goodbye my friend it's hard to die. When all the birds are singing in the sky. Now that spring is in the air. Pretty girls are everywhere.

Hydrogen bonds hold DNA strands together. Nitrogenous bases are between these two strands that link together in a specific manner with different types of hydrogen bonds. A DNA molecule is made up of the sugar deoxyribose, a phosphate group and complementary nitrogenous base pairs. The double strand of the helix consists of the sugar-phosphate backbone. The nitrogenous base pairs, which are linked by hydrogen bonds that also hold the strands together, are between this backbone. However, the nitrogenous bases, which are adenine, thymine, cytosine and guanine, pair up so that cytosine only pairs with guanine and adenine links up with thymine.
