DNA is found in nearly all living cells ... another polynucleotide by way of special chemical bonds called hydrogen bonds. This base-to-base bonding is not random; rather, each A in one strand ...

These pairs are called base pairs and they connect the two sugar-phosphate backbones through interactions called hydrogen bonds. In cells, the DNA helix is often overwound, causing a phenomenon ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

the helix structure is unwound special 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 ...
