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.
Thymine, cytosine, adenine and guanine (often referred to as T, C, A and G) are the foundational units of the genetic code in all living organisms. It is in these bases and the patterns in which they are arranged along the DNA backbone that all the information for an organism to function is contained.
