It turns out that there is an organism that has matching mistakes in its beta-globin pseudogene. 后来发现有一种生物具有与人类相匹配的“β球蛋白假基因遗传错误”。
But if the gene copy contains disabling typos or is missing pieces of the original, such as the promoter, it will become a pseudogene. 但如果基因出现短缺(像是缺失启动子)或序列发生错误使基因损坏,它们就成了伪基因。
Pseudogenes are functionless relatives of genes that have lost their gene expression in the cell or their ability to code protein. Pseudogenes often result from the accumulation of multiple mutations within a gene whose product is not required for the survival of the organism. Although not protein-coding, the DNA of pseudogenes may be functional, similar to other kinds of non-coding DNA which can have a regulatory role.
