Genetic Mutation Flashcards
What is a genetic mutation?
A permanent change in the gene sequence.
How can genetic mutation affect the organism?
Either visibly or without an obvious effect.
A genetic mutation can prevent a gene from?
Functioning properly.
What is DNA repair?
A collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome.
Mutation can involve?
Large new sections of DNA.
Mutations can be?
Beneficial, harmful or neutral.
How can genetic mutation affect natural selection and evolution?
- beneficial mutations change the gene pool
- chances of reproduction increase
- mutated gene inherited
What is a gene pool?
The total genetic diversity found within a population or species.
How does genetic mutation cause different species to emerge?
If the mutation is different enough from the original, this will cause a new species to be produced.
