The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they ...

2024 — Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked. In 1948, Linus Pauling discovered that many proteins take the shape of an alpha helix ...

Water molecules are so attracted to each other that even after the balloon pops, the water molecules stay together keeping the shape of the balloon. In the water molecule, the oxygen and hydrogen ...

Wilkins and Franklin used X-ray diffraction as their main tool -- beaming X-rays through the molecule yielded a shadow picture of the molecule's structure, by how the X-rays bounced off its ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

making it difficult to capture the unique shapes of individual RNA molecules. Historically, scientists believed that obtaining 3D images from a single molecule was impossible due to weak signals. "It ...
