When invisible changes matter: how DNA mutations affect our lives<\/strong><\/h2>\n

Each of us has a unique code hidden within us \u2014 DNA<\/strong>, which determines what we will be: our appearance, abilities, predispositions to diseases. And although this code seems stable, it is not immune to errors. Sometimes - accidental, sometimes - caused by external influences. Such changes in the genetic code, or mutations<\/strong>, can go unnoticed, but sometimes they change everything: they cause disease, affect the body's response to medications, or are passed on to subsequent generations.<\/p>\n

Today, when genetics has become part of personalized medicine<\/strong>, Understanding what DNA mutations are is an important step towards taking control of your own health. In this article, we'll look at exactly how these changes occur, what makes them dangerous, and how to detect them.<\/p>\n

Main types of DNA mutations<\/strong><\/h2>\n
\n\n\n\n\n\n\n\n\n\n\n
Type of mutation<\/strong><\/th>\nDescription<\/strong><\/th>\n<\/tr>\n<\/thead>\n
Dotted<\/strong><\/td>\nReplacing one nucleotide with another (e.g., A is replaced with G)<\/td>\n<\/tr>\n
Deletions<\/strong><\/td>\nLoss of one or more nucleotides<\/td>\n<\/tr>\n
Insertions<\/strong><\/td>\nAdding extra nucleotides to a DNA sequence<\/td>\n<\/tr>\n
Duplicates<\/strong><\/td>\nDoubling a section of DNA<\/td>\n<\/tr>\n
Inversions<\/strong><\/td>\nChanging the order of genetic material within a chromosome<\/td>\n<\/tr>\n
Translocations<\/strong><\/td>\nExchange of DNA segments between different chromosomes<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Mutations can be hereditary<\/strong> (inherited from parents) or acquired<\/strong> (occurring throughout life, for example, under the influence of radiation, viruses or toxins).<\/p>\n
