What are pseudogens?
pseudogens are DNA cuts that look like genes, but do not behave like genes because they are unable to rewrite. Transcription is the first step in the expression of the gene and if the DNA segment is unable to perform transcription, it is non -functional. Because pseudogens are inoperable, some people combine them so -called "unsolicited DNA" that perform any function, but because they have some features associated with genes, they have a great scientific interest. Just because they don't work, in other words, they don't mean they have nothing to say.
Several processes can lead to the creation of pseudogen. Sometimes the mutation causes the gene to become inactive and damages DNA so that it is no longer capable of transcription and mutation can be handed over and amplified in certain populations. These pseudogens are known as "disabled". If it has enough mutation population, the gene will eventually cease to expresses completely in this population, causing the all -way genetic property to disappear. The DNA segment will be non -functional, but may look like a complete gene. Uncovered pseudogens with VyskThey yield when genes replicate and one of the replicas becomes broken thanks to mutation. Over generations, DNA gradually disintegrates even further and eventually turns into a real spam.
The main reason why pseudogens are interesting is that they can reflect evolutionary shifts and reveal information about relations between different organisms. For example, two types of large cats can be traced to common ancestors using pseudogenes, and scientists are looking for similar lengths of genetic material to determine when the species began to divide. Pseudogenes can also be used with the evolutionary history of the body, and scientists are looking for inactive genes that code properties that no longer appear. Pseudogens can be compared with information coded on the movie side; It cannot be seen in the finished picture, but provides valuable information for those who know where to look.
by definition, this genetic material is non -functional. However, it is fromWe are activating pseudogen, most often in malignancies, where something triggers the activation of the extinct gene. Scientists have noted that pseudogens are sometimes involved in the development of certain cancers, so the activation process of interest for people working in the treatment and prevention of cancer.
