WE have formulated a structure for the nucleic ... the sense of a right-handed screw. The phosphate groups are closely packed about the axis of the molecule, with the pentose residues surrounding ...

Each of these things — along with every other organism on Earth — contains the molecular instructions ... looks much like a ladder with sugar-phosphate side supports and base-pair rungs.

Scientists still needed to figure out this molecule's structure to be sure ... This had helped her deduce that the phosphate part of the molecule was on the outside. Watson returned to Cambridge ...

(It takes two bases to form a rung -- one for each side of the ladder.) A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide. Nucleotides are abundant in the ...

The reaction product is adenosine diphosphate (ADP), and the phosphate group either ends up as orthophosphate (HPO 4) or attached to another molecule (e.g. an alcohol ... and then elaborated its 3 ...
