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 ...

Free RNA nucleotides form hydrogen bonds with the ... Peptide bonds form between the adjacent amino acids to finalise the structure.
