We have also analyzed the nucleotide and deduced amino acid sequences of mitochondrial genes , the formation cause of a pseudogene for trnamel , and proposed the secondary structures of 22 trna genes 我们还分析了基因组的碱基和氨基酸的组成、 trna ~ ( met )假基因的成因,推测了22个trna的二级结构。
Pseudogenes are dysfunctional relatives of genes that have lost their protein-coding ability or are otherwise no longer expressed in the cell. Pseudogenes often result from the accumulation of multiple mutations within a gene whose product is not required for the survival of the organism.
