How are the mutations in a genome similar to printing a book?

Mutations in a genome can be likened to errors in printing a book. Just as a typo or misprint can change the meaning of a sentence, a mutation can alter the sequence of DNA, potentially affecting the function of genes. Some mutations may have no effect, like minor spelling mistakes, while others can lead to significant changes, akin to a chapter being rewritten. In both cases, the original content is modified, leading to variations in the final product.
