An Athenian fleet had been driven ashore at Pylos by a storm, and, at the instigation of Demosthenes, the Athenian soldiers fortified the peninsula, and a small force was left there when the fleet departed again.
According to the official Guidelines for Human Gene Nomenclature, a gene is defined as a DNA segment that contributes to phenotype/function. In the absence of demonstrated function a gene may be characterized by sequence, transcription or homology.. Genes are composed of DNA, a molecule in the memorable shape of a double helix, a spiral ladder. Each rung of the spiral ladder consists of two paired chemicals called bases.
Best Answer: E.nucleotides A gene is a segment of DNA that codes for the production of a functional polypeptide or RNA. DNA consists of many nucleotides linked together (by 3', 5' phosphodiester bonds). So a gene is made of nucleotides. C. chromosomes That's wrong. A gene is a small segment of a chromosome, so is not made of chromosomes. Consider that humans have about 21,000 genes, but only 23 chromosome pairs. Clearly, a chromosome can contain hundreds of genes.
