Such probes are sensitive, even to single base differences in target DNA. Freed from the constraint of needing hydrogen bonding to achieve rapid, high-fidelity DNA synthesis, one may be able to ...

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 ...

an energy currency that can be scarce—so instead of covalent bonds, which are more permanent because they require more energy to sunder, DNA strands are held together by delicate hydrogen bonds ...

(Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base pair, named after James Watson and Francis Crick, who first proposed the double helix structure of ...

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 ...

One of the most important properties of guanine is its ability to form three hydrogen bonds with cytosine. This strong base pairing is crucial for the stability of the DNA double helix and the ...

Cells express their genes by converting the genetic message into protein. This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed ...
