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.
DNA is made up of chromosomes and proteins. These chromosomes contain specific codes from your parents genes that come together and determine your characteristics.The genes in DNA that you receive are determined by if there are recessive or dominant. piece of DNA coding for a protein is called a gene. When the protein is produced, we say that the gene is expressed. Now a brain cell and a white cell have the same DNA, but they are very different because during and after their development, they express different genes.
