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.

1. The DNA double helix is held together by two types of bonds, covalent andhydrogen. Covalent bonds occur within each linear strand and strongly bond thebases, sugars, and phosphate groups (both within each component and betweencomponents).It is the 3Â´ -OH group thatis required to create the next phosphodiester bond.) The RNA is subsequentlyremoved and replaced with DNA so that no gaps exist in the final product. 4. Helicases are enzymes that disrupt the hydrogen bonds that hold the two DNAstrands together in a double helix.
