Pseudogenes are defective copies of functional genes. These may be partial or complete duplicates derived from polypeptide-encoding genes or RNA genes. The DNA sequence of a pseudogene is characteristically very similar to its functional counterpart,...

A pseudogene is a sequence of DNA that is very similar to a normal gene but that has been altered slightly so that it is not expressed. A pseudogene was probably once functional. However, the accumulation of mutations over time rendered it incapable of...

Pseudogenes are defunct relatives of known genes that have lost their protein-coding ability or are otherwise no longer expressed in the cell.[1] Although they may have some gene-like features (such as Promoters, CpG islands, and splice sites), they are...
