Demosthenes had five triremes and their complements of soldiers as a garrison, and was reinforced by 40 hoplites from a Messenian ship that happened to stop at Pylos.
Individual codons code for specific amino acids. A gene is a sequence of nucleotides along a DNA strand-with 'start' and 'stop' codons and other regulatory elements-that specifies a sequence of amino acids that are linked together to form a protein.
This contains all of our genes. DNA, itself is made up of four chemical bases, pairs of which form the rungs of the twisted, ladder-shaped DNA molecules. These four molecules are adenine (A), thymine (T), cytosine (C), and guanine (G).
