Our body is a true miracle. However, it can only function if the proteins produced on the basis of the DNA do not have any defects and fulfill their tasks as workers and building materials of the cells as planned. But sometimes misspellings occur in DNA. These errors are called mutations.<\/p>\n
-Damage can occur in different places in the. If they don’t fix them, mutations occur:<\/p>\n
One in a cell is passed on to the daughter cells. If only affected by the mutation, the person gets sick, but does not pass the mutation on to his or her offspring. For example, tumors arise from defective cells that proliferate without control.<\/p>\n
However, if (i.e. sperm or egg cells) carry a mutation, this is passed on from parent to child during reproduction. In cystic fibrosis, the child must have the corresponding mutation from both parents for the disease to occur (recessive ). For other diseases, it is sufficient if only one parent passes on the mutation (dominant inherited disease).<\/p>\n
However, unrepaired mutations do not always have to have dire consequences. Many mutations happen in areas of DNA that are irrelevant to protein production and thus have no consequences. In addition, our body has two copies of each chromosome (one from the mother and one from the father). If there is a mutation on one of them, often the second, healthy chromosome can compensate for the error. In the next generation, of course, there is a risk of inheriting the mutation twice (once from the mother and once from the father).<\/p>\n
Last but not least: The fact that spontaneous changes occur in the genetic material is an important mechanism of the ! For if a living being suddenly becomes more successful than its fellow species through a mutation, it has better chances of survival and produces more offspring. By passing on positive mutations to offspring, better-adapted populations – or even new species – are created.<\/p>\n","protected":false},"excerpt":{"rendered":"
