染色体突变, 染色体变化
a genetic change that can affect chromosome structure or number, leading to variations in gene expression and potential genetic disorders
A chromosomal mutation is a change in the structure or number of chromosomes in a cell. Chromosomes, which are made up of DNA and proteins, contain genetic information that guides an organism's growth and development. A mutation can occur when there is a change in the DNA sequence or an abnormality in the number of chromosomes. This can lead to various effects, such as genetic disorders or diseases. For example, Down syndrome is caused by an extra copy of chromosome 21. Chromosomal mutations can happen spontaneously or be caused by environmental factors.
