How do the bases bond together dna
WebBecause of the sizes and functional groups of the bases, base pairing is highly specific: A can only pair with T, and G can only pair with C, as shown below. This means that the two strands of a DNA double helix have a very predictable relationship to each other. WebSpecial molecules break the weak hydrogen bonds between bases, which are holding the two strands together. This process occurs at several locations on a DNA molecule. Stage two DNA...
