Each pore holds a string of water molecules centred at kinked helices in two inverted-repeat triple-helix bundles (THBs).
Each subunit possesses an apparent ion conduction pathway, which in the structure at the highest resolution (1.6 Å) is marked by a string of water molecules.
In the native C-ACE structure, and in all previously studied C-ACE inhibitor-bound complexes [ 27, 28, 30, 31], this binding site of FII-B is occupied by a string of bound water molecules.
Molecular synthesis requires a string representation of molecules.
An average-sized protein macromolecule contains a string of about 400 amino acid molecules.
With the help of several different molecules, a string of amino acids forms according to the order of the mRNA bases, which are very similar to DNA bases.
Much of the cell's energy is stored in molecules called ATP, which contain a string of three phosphate groups joined to an organic molecule.
Each person's DNA, or genetic code, consists of a string of three billion "base pairs," or large molecules, represented by the letters A, G, C, and T. The sequencing of those four base pairs creates the code for all human characteristics, and variations in those sequences make one person different from another.
The DNA molecule is modelled as a string of nucleotides, which leads to specific affinity between a TF molecule and DNA at the position where the molecule is bound.
But you do a trick, you put little dye molecules, florescent molecules; think of it as a string of Christmas tree lights.
In this model, each TF molecule is represented as an agent able to perform certain actions and the DNA molecule as a string of the nucleotides: a, t, c or g.
