Double-helix molecules are frequently encountered in biological and synthetic organic systems, where they typically provide improved strength and better electrical properties relative to materials ...

Rediscovered letters and postcards highlight the fierce competition among scientists who discovered DNA's famous double-helix structure and unraveled the genetic code. Francis Crick and James D.

In geometry a double helix (plural helices) typically consists of two congruent helices with the same axis, differing by a translation along the axis, which may or may not be half-way. The term ...

We know DNA unzips to replicate itself, each new double helix containing half the parent. But how do we know that? An incredible experiment, conducted in the 1950s, proved how DNA replicated itself ...

DNA may contain the blueprint for life but it takes proteins to read the plan and build an organism. The mechanism of this vital biological process has remained a mystery but now researchers in France ...

Exactly 66 years ago, on April 25, 1953, Francis Crick and James Watson published their famous article that showed that the shape of DNA is a double helix. They weren’t able to see DNA directly - it’s ...

In eukaryotic cells, chromosomes are made up of DNA. DNA can also be found in the chloroplasts and mitochondria, and inside the cytoplasm in the form of plasma. DNA molecules consist of nucleotides ...

Science is about building the future. Discovering new mechanisms that operate in nature, inventing new tools of investigation and elaborating new concepts are the core of scientific practice. Then why ...
