1 A steam turbine consists of a rotor resting on bearings and enclosed in a cylindrical casing. The rotor is turned by steam impinging against attached vanes or blades on which it exerts a force in the tangential direction.
A gene is a segment of DNA that encodes function. A chromosome consists of a long strand of DNA containing many genes. A human chromosome can have up to 500 million base pairs of DNA with thousands of genes.he total complement of genes in an organism or cell is known as its genome, which may be stored on one or more chromosomes. A chromosome consists of a single, very long DNA helix on which thousands of genes are encoded. The region of the chromosome at which a particular gene is located is called its locus.
Gene-what is, definition and function. Gene is a segment of coding DNA (DNA that instructs the structure and function of cells throughout the body) composed of a specific sequence of nucleotides.The gene is the basic unit of inheritance that directs every facet of the bodyâs appearance and functions. Genes align along chromosomes in pairs.Each CHROMOSOME (AUTOSOME) contains thousands of genes, except the sex chromosomes which contain only a few hundred genes. Each gene has a specific location on the chromosome, called its locus, and encodes a specific function (either a protein or RNA transcription).enes align along chromosomes in pairs.
