All the latest science news on dna double helix from Phys.org. Find the latest news, advancements, and breakthroughs.

Double-stranded DNA is composed of two linear strands that run opposite to each other, known as anti-parallel strands; these strands twist together to form a double helix. The structure of DNA can ...

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 ...

The DNA molecule encodes all information using four chemical bases: cytosine (C), guanine (G), adenine (A) and thymine (T). It has two complementary strands, each with a long sugar–phosphate ...

In both cases, the mechanism is based on a structural transition of DNA molecules--a change from one conformation (such as the usual double helix) to another. Conventional DNA is a right-handed helix.

Chemical tag marks future microRNAs for processing, ... Just as two DNA strands naturally arrange themselves into a helix, DNA's molecular cousin RNA can form hairpin-like loops.

James Watson and Francis Crick proposed that DNA (deoxyribonucleic acid) was a double-helix structure, not a triple stranded structure as had been previously hypothesized, on April 2, 1953. The ...

Eggs and embryos from people with polycystic ovary syndrome have altered patterns of so-called epigenetic tags, which could ...

Just as two DNA strands naturally arrange themselves into a helix, DNA’s molecular cousin RNA can form hairpin-like loops. But unlike DNA, which has a single job, RNA can play many parts - including ...
