gene mutation

• Modification permanente dans la séquence d'ADN d'un gène, pouvant entraîner des changements dans la structure ou la fonction des protéines et être à l'origine de troubles génétiques ou de variations.

A permanent alteration in the DNA sequence of a gene, which can result in changes to the structure or function of proteins and may lead to genetic disorders or variations.

1. Change in DNA sequenceB2formal

   A permanent alteration in the nucleotide sequence of a gene, which can affect the function of the gene and potentially lead to disease or variation.

   Mutation génique

   • A gene mutation can cause a protein to be produced incorrectly.
   • Scientists identified a specific gene mutation linked to the disease.
   • Some gene mutations are inherited from parents, while others occur spontaneously.

2. Source of genetic variationB2formal

   A change in the genetic material that can be neutral, harmful, or beneficial, and is a driving force of evolution.

   mutation génique

   • Gene mutations provide the raw material for natural selection.
   • Most gene mutations are harmless and have no noticeable effect.
   • The study examined how gene mutations accumulate over generations.
