  • zh基因突变是基因DNA序列发生的永久性改变,可能导致蛋白质结构或功能的变化,并可能引起遗传疾病或个体差异。

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.

    zh基因突变

    • 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.

    zh基因突变的来源

    • 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.
