Beyond the ladder-like structure described above ... Franklin interpreted them as representing distances between the nucleotides that were arranged in a spiral shape called a helix.

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA ... was made up of two chains of nucleotides paired in such a way to form a ...

Scientists still needed to figure out this molecule's structure to be sure ... suggesting the molecule was made of two chains of nucleotides, each in a helix as Franklin had found, but one ...

A nucleic acid is a long molecule made up of smaller molecules called nucleotides. Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a ...

In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with C) to form the iconic double helix structure. RNA is usually single-stranded but ...

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
