During DNA replication, the classic double helix can temporarily rearrange into an alternative structure known as a DNA three ...

Folding DNA Into Tiny Circuits. August 21, 2009 1:00 PM ET. ... As you recall, DNA normally exists as a duplex, two single strands wrapped together in the famous double helix.

This is because if you trace the backbone of DNA along the helix, you will find that after every half-turn, the strands fold back. These differences are illustrated in the diagram below.

Dec. 9, 2024 — Helical structures are ubiquitous across biology, from the double-stranded helix of DNA to how heart muscle cells spiral in a band. Inspired by this twisty ladder, researchers ...

By creating a more true-to-life representation of DNA's environment, researchers at Northwestern University have discovered that strand separation—the essential process a "resting" double helix ...

As a result, the translocated DNA double helix will necessarily split and unwind, an effect known as unzipping. The research team, which also includes Antonio Suma from the University of Bari, ...

Artist's impression of the DNA double helix structure. We are increasingly learning that these DNA strands can be unzipped to form new structures, affecting which genes are turned on and off in a ...

The book is "The Secret of Life: Rosalind Franklin, James Watson, Francis Crick, and the Discovery of DNA's Double Helix." Howard Markel, always great to see you. Dr. Howard Markel: ...

By creating a more true-to-life representation of DNA's environment, researchers at Northwestern University have discovered that strand separation - the essential process a "resting" double helix ...

New research predicts the location of DNA sequences that can form structures besides the canonical double helix — non-B DNA — in the recently released telomere-to-telomere genomes of the great ...

The most famous image to emerge from 20th-century biology is the deoxyribonucleic acid (DNA) double helix, illustrating the structure of the gene, life’s genetic material.
