Precipitation occurs when adjacent DNA helices are affected simultaneously, with the compaction agent not only reducing the helix-helix repulsion but also bridging the helixes. This phenomenon was ...

Liquid crystals exist in a phase of their own. They can flow like liquids, but because their molecules are arranged in a ...

The angle between the gripper's two main structural elements can be controlled with DNA helices. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to ...

Why is the heart slightly on the left side of the body for most people? Why is DNA almost always a right-handed helix? Same with alpha helices, the building blocks of proteins. Chirality, or ...

Figure 2: New research shows that by using a new method called triplex origami one can create triple DNA helices that can bend or "fold" DNA in into compact structures. Illustr: Minke A. D. Nijenhuis ...

Detection of mutations and damaged DNA bases is important for the early diagnosis of genetic disease. Here we describe an electrocatalytic method for the detection of single-base mismatches as ...

Francis Crick and James Watson with a model of the DNA molecule At midday on 28 February 1953, Francis Crick and James Watson walked into The Eagle pub in Cambridge and announced “We have ...

But what came before that remains unclear. Double-stranded DNA helices are great for storing genetic information. Many of ...

Testing your DNA is easier than ever with an abundance of at-home DNA tests on the market. All you need to do is provide a simple DNA sample to learn more about your heritage and family history.

How Do At-Home DNA Kits Work? Most at-home DNA testing kits use saliva and provide a collection kit. Once you send your collection kit back to the company, they will likely either send it to a ...

Until recently, wildlife surveys would involve going out and physically looking for species such as plants, birds or mammals. But now we can also use DNA sequencing technologies to monitor wildlife, ...

Ancient Viral DNA in the Human Genome Linked to Multiple Sclerosis and Amyotrophic Lateral Sclerosis Oct. 21, 2024 — New research has revealed a connection between ancient viral DNA embedded in ...
