snoRNA host genes

SnoRNA host genes are genes that contain within them a special type of small RNA called snoRNA (small nucleolar RNA). These snoRNAs are important for modifying other RNA molecules, like guiding chemical changes to maintain their function. The host gene acts as the template from which snoRNA is produced. Essentially, the host gene provides the starting material and environment for snoRNA to be created and then function within cells, often playing a role in the cell's overall management of RNA and protein production.
