Pseudogenes are non-functional DNA sequences that resemble their active, or 'true', gene counterparts.
这些是无功能的DNA序列,它们看起来像其活跃或"真正的"基因。
The
pseudogene has lost its coding ability through mutations over time, rendering it a silent genetic relic.
随着时间的推移,伪基因由于突变失去了编码能力,成为了沉默的遗传遗迹。
Comparative genomics has revealed that many
pseudogenes were once functional but became inactivated due to evolutionary processes.
比较基因组学显示,许多伪基因曾经是功能性的,但因进化过程而失活。
Pseudogenes can serve as regulatory elements, influencing the expression of neighboring genes without themselves being expressed.
伪基因可以作为调控元件,影响相邻基因的表达,而自身不被表达。
Some
pseudogenes may have evolved to mimic their active genes for regulatory purposes, providing an evolutionary advantage.
有些伪基因可能进化成模仿活跃基因以达到调节目的,这为进化提供了优势。
Scientists have discovered that certain
pseudogenes can undergo reactivation and regain their functionality under specific conditions.
科学家发现某些伪基因在特定条件下可能会重新激活并恢复其功能。
Genetic studies often exclude
pseudogenes from analysis, as they do not contribute to protein production and can introduce misleading results.
基因研究通常会排除伪基因,因为它们不参与蛋白质生产,并可能导致误导性结果。
The presence of multiple
pseudogenes within a genome is a common phenomenon, reflecting the complex history of gene duplication and evolution.
在一个基因组中存在多个伪基因是一种常见现象,反映了基因复制和进化的复杂历史。
The study of
pseudogenes provides insights into the evolutionary processes that shaped our genetic code and the potential for functional changes in the future.
研究伪基因有助于理解塑造我们遗传密码的进化过程,以及未来可能的功能变化。
While
pseudogenes may seem like evolutionary dead ends, some researchers propose that they could still have functional roles in cellular processes under certain circumstances.
尽管伪基因看似进化上的终点,但一些研究者提出它们在特定条件下仍可能在细胞过程中发挥作用。
