to the backing plate by a bonding process in which the friction material is subjected to both heat and pressure. Underlayers can be inserted between the friction material and backing plate to improve bond strength and other properties. Drum brake linings consist of the friction material itself, usually shaped to match the radius of the brake shoe onto which it is subsequently attached. The friction material is usually attached to the
The 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.
Here are two locations for the HEXA gene. Cytogenetic Location: 15q23-q24 (The HEXA gene is located on the long (q) arm of chromosome 15 between positions 23 and 24. Each chromosome is divided into two sections called 'arms'.ere are two locations for the HEXA gene.
