DNA’s iconic double helix has long been the symbol of life’s blueprint. However, the human genome conceals far more complexity. Among these mysteries are i-motifs, unusual knot-like 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 ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

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 ...

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 ...

Understanding this structure is essential for studying heredity and genetic information. (Image: National Human Genome Research Institute) The discovery of DNA and its double-helix structure was a ...

Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

The DNA molecule was composed of the traditional sugar backbones and nucleotide pairs, but rather than the well-known right-handed spiral of the double helix structure, famously discovered by Watson ...

The double helix unwinds, and each strand serves as a template for the synthesis ... has helped solve countless criminal cases. DNA evidence can also be used to establish paternity, identify human ...
