Question: Gene nomenclature has been established by the HUGO Gene Nomenclature Committee (HGNC) for each known human gene in the form of an approved gene name and symbol (short-form abbreviation), which can be accessed through a database maintained by HGNC. Symbols are chosen to be unique, and each gene has only one symbol (although approved symbols sometimes change). Symbols are preferably kept consistent with other members of a gene family and with homologs in other species, particularly the mouse due to its role as a common model organism.

Answer: What committee has established gene nomenclature for every known human gene?

Question: The Homestead Act of 1862 provided free land to settlers who could claim and "prove-up" 160 acres (0.65 km2) of federal land in the midwest and western United States. Montana did not see a large influx of immigrants from this act because 160 acres was usually insufficient to support a family in the arid territory. The first homestead claim under the act in Montana was made by David Carpenter near Helena in 1868. The first claim by a woman was made near Warm Springs Creek by Miss Gwenllian Evans, the daughter of Deer Lodge Montana Pioneer, Morgan Evans. By 1880, there were farms in the more verdant valleys of central and western Montana, but few on the eastern plains.

Answer:
What year did the Homestead Act provide land to settlers?
