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.
The order (or sequence) of these four bases determines each genetic code. The segments of DNA that contain the instructions for making specific body proteins are called genes. Scientists believe that human DNA carries about 25,000 protein-coding genes. Each gene may be thought of as a recipe you'd find in cookbook.
