The primary molecule of inheritance in nearly all organisms; a double-stranded polymer of nucleotides that contains the sugar deoxyribose; abbreviated as DNA.

In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...

The signature imagery of two DNA strands locked around each other is one that everyone has seen in school. And, everyone was also taught that the double helix shape with the strands are bound by ...

Not all DNA is in the double helix form described in textbooks since the 1950’s. Quadruple helix DNA, also known as G-quadruplex DNA, was identified in the human genome several decades ago, and ...

so that matching base pairs interlocked in the middle of the double helix to keep the distance between the chains constant. Watson and Crick showed that each strand of the DNA molecule was a ...

Homologous recombination plays essential roles in the repair of DNA double strand breaks (DSBs) and collapsed replication forks. The fundamental reaction in homologous recombination is the exchange of ...

The backbone of the DNA double helix consists of alternating phosphate and deoxyribose sugar molecules. Interlinking bases hold the two sides together. As A is complementary to T and C is ...

Kossel was later awarded the Nobel Prize in Physiology or Medicine in 1910 for his contributions to the understanding of nucleic acids and proteins. During DNA replication, the double helix unwinds, ...

When it comes to her place in the history of the double helix's delineation ... such as might have brought her to the structure of DNA faster than Watson and Crick? Elkin: I don't think she ...

One film that successfully depicts the competitive nature of scientific research and the sacrifices that scientists make for their careers is Life Story: The Race for the Double Helix, a 1987 made-for ...

Deoxyribonucleic acid (DNA) is the information-carrying molecule found in all living organisms. In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like ...

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 ...
