This is most likely an example of a mutation.
Mutation is any alteration or change in DNA sequence which affects the genetic instruction carried by that gene. Mutation can occur either as a result of errors during DNA replication or due to environmental factors such as cigarette smoke and ultraviolet (UV) radiation. Mutations are heritable, especially if they have a positive effect. The disorder Down syndrome is an example of mutation which occurs due to error in cell division in which there is extra copy of a genetic material (specific chromosome); chromosome 21.

Macromolecules are biomolecules which are needed by the body to function. In a cellular level, these are used by the cell to perform many of its processes such as transport, ATP generation and protein synthesis. There are four macromolecules which are carbohydrates, proteins, lipids and nucleic acids. Carbohydrates are obtained by eating for instance sugars or sugary-related goods. Proteins are gained through meat and lipids, oil and fish. Nucleic acids on the other hand are formed through proteins.
