Fair Labor Standards Act - FLSA. A maintenance worker is hired to work 35 hours at $15/hr. At $525/week, he passes the salary test (his income is greater than $455/week) but, as he cannot exercise discretion or independent judgment and is directly supervised, he is classified as a non-exempt employee.
Although Hox genes contain and are originally named because of the homeobox sequence, not all homeobox-containing genes are Hox genes (other examples include the POU genes and CDX genes). The homeobox encodes for a protein sequence called the homeodomain, which is a DNA-binding domain.
So for example, a Hox gene product may activate the gene inside a developing insect that will specify structures on its thoracic region, or a Hox gene product may repress a gene involved in the development of the antenna. Hox genes are also sometimes referred to as homeotic selector genes.
