What term describes the changing of the structure of a gene?

• A. Mutations
• B. Chromosome
• C. Evolution
• D. Proteins

Answer: (A)

Mutations describe a change in the DNA sequence that makes up a gene. Since a gene’s structure is defined by the order of its nucleotides, any substitution, insertion, or deletion alters that structure. This can change how the gene works or how its product, usually a protein, is made. A chromosome is a larger unit that contains many genes, evolution is changes in populations over generations, and proteins are the products a gene helps create. So, the term for changing the structure of a gene is mutation. Some mutations happen by chance, some from environmental factors, and they can be inherited if they occur in reproductive cells.
