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 globin genes encode the globin chains that make up hemoglobin (Hb). More than 1000 polymorphic variants of the globin genes have been characterized, consisting of single nucleotide substitutions through to complex gene rearrangements.
