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 ...

so that matching base pairs interlocked in the middle of the double helix to keep the distance between the chains constant. Watson and Crick showed that each strand of the DNA molecule was a ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

Scientists have tapped into the Summit supercomputer to study an elaborate molecular pathway called nucleotide excision ...

Here is a view of the double helix -- the subject of Rosalind ... is a special kind of DNA known as Z-DNA. The DNA molecule is made up of four bases -- adenine (A), cytosine (C), guanine (G ...

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren't just skin deep. Inside the body, DNA is literally being torn ...

Researchers at Georgia State University used the Summit supercomputer to study an elaborate molecular pathway called ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer.

Base pairing is a very specific process which can be used to design matching strands. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert ...

A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.
