Final answer:
A mutation is a D. genetic change in an organism's DNA that can lead to new traits or diseases. It can be inherited or caused by environmental factors and affects proteins' structure and function.
Step-by-step explanation:
A mutation is a genetic change in the DNA sequence that can lead to differences in the phenotype of an organism. Mutations can be inherited, as in some cancers and genetic disorders like cystic fibrosis, or they can be caused by environmental factors such as radiation or certain chemicals. A mutation in a gene can result in an altered amino acid sequence in a protein, potentially affecting the protein's structure and function, which can result in diseases such as cancer or create a new trait within an organism.
A mutation is a heritable change in the DNA sequence of an organism. It can lead to the development of a new trait or cause an altered phenotype compared to the wild type. Mutations can occur in genes that regulate the cell cycle, leading to conditions such as cancer. Genetic disorders are also caused by mutations in one or more genes.
