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 chains of nucleotides in a nucleic acid are linked by 3', 5' phosphodiester linkages. Nucleic acids may be in the form of DNA or RNA molecules containing the genetic information important for all cellular functions and heredity.
