unlike the double-helix of DNA. RNA molecules are also significantly shorter in length. Despite these differences, both types of nucleic acid are made from the same basic parts. Nucleic acids are ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

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 ...

Shortly after, Watson and Crick made a crucial advance when they proposed that the DNA molecule was made up of two chains of nucleotides paired in such a way to form a double helix, like a spiral ...

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 ...

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred to as non-B DNA—have been implicated as regulators of cellular ...

Now, collaborating with Jim Watson, who had returned from Cambridge, I was taken with a challenge put forth in his famed double-helix manuscript. 1 In their 1953 publication on the DNA double helix, ...

The Race for the Double Helix, a 1987 made-for-television film that dramatizes the discovery of the structure of DNA by the legendary duo James Watson and Francis Crick in 1953. The film stars Jeff ...

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 ...
