genetic mutation

• Постоянное изменение в последовательности ДНК, составляющей ген, которое может привести к изменениям в структуре или функции организма, иногда вызывая заболевания или эволюционную адаптацию.

A permanent alteration in the DNA sequence that makes up a gene, which can result in changes to the structure or function of an organism, sometimes leading to disease or evolutionary adaptation.
