pseudogenizáció
Pseudogenizáció is a biological process where a functional gene is inactivated and evolves into a pseudogene. Pseudogenes are DNA sequences that are similar to known genes but have lost their biological function due to mutations. These mutations can include deletions, insertions, or point mutations that disrupt the gene's coding sequence, its regulatory elements, or its ability to be transcribed into RNA.
There are several mechanisms that can lead to pseudogenization. Duplication is a common starting point, where
Pseudogenes were once thought to be "junk DNA," evolutionary remnants with no purpose. However, recent research
