Chances are you've seen an illustration of DNA's double-helix structure and even pictures ... Each sugar-phosphate-base combination is called a nucleotide. A nucleotide is made up of 30 atoms ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Each nucleotide consists of alternating sugar and phosphate sections with one of the four different bases attached to the sugar.

For example, during replication, a thymine nucleotide ... in the molecular structure of nucleotides, ultimately causing substitutions, insertions, and deletions in the DNA sequence.
