pseudogenes
Pseudogenes are non-functional relatives of known functional genes, which have lost protein-coding ability or are no longer expressed in the cell.
Pseudogenes may have some gene-like features, such as promoters, CpG islands, and splice sites, yet are nonfunctional in that they lack protein-coding ability. This loss of gene function results from stop codons, frameshifts, lack of transcriptional capacity, or from an inability to function as an RNA (as with rRNA pseudogenes).
