Mutations

Mutations. General Definition Long Notes : Any change in DNA sequence is called a mutation. Abbreviated Notes (AN) : Mutation (mut) = DNA sequence (seq) change. General Definition. General Definition Long Notes : Mutations may affect only one gene, or they may affect whole chromosomes.

Mutation: Any change or error in DNA

Mutation: Any change or error in DNA. What determines whether mutations are passed on to offspring?. If mutations occur in reproductive cells, the altered gene will become part of the genetic makeup of the offspring.

Mutations

Mutations. What is a Mutation?. A mutation is a change in the DNA sequence. Genetic mutations, which affect reproductive cells, can be passed on to offspring. Somatic mutations, which affect other cells, cannot be passed on. What Causes Mutations?.
