Genetic disorders are caused by mutations in the DNA sequence from "summary" of NCERT Exemplar Problems-Solutions BIOLOGY class 12th by Arihant Experts
Genetic disorders are caused by mutations in the DNA sequence. These mutations can be inherited from parents or acquired during an individual's lifetime. Mutations can occur in any of the genes that make up an organism's DNA, leading to changes in the proteins that are produced by those genes. These changes can disrupt normal cellular functions and lead to the development of genetic disorders. Mutations can take many different forms, including changes in a single nucleotide (called point mutations), deletions or insertions of nucleotides, or rearrangements of larger sections of DNA. The effects of these mutations can vary depending on where they occur in the DNA sequence and what genes are affected. Some mutations may have no effect on an individual's health, while others can cause severe genetic disorders. Genetic disorders can be classified into dif...
