Okay, I am going to do your thing right here.

Answer 2

DNA is made of two strands wrapped together. Each strand has a row of "base pairs", made of cytosine, guanine, thymine and adenine. Cytosine always pairs with guanine, and adenine with thymine, each strand is a negative image of the other. This means that each strand can serve as a template for the whole. The two separate, and the opposing base pairs line up against each set's base pairs. The new strand is knitted together to make one long strand that coils around its neighbor. This happens to both of the original strands, turning one double strand into two single strands and then into two identical double strands.
