how are auxotrophic mutants detected?
431607
Auxotrophic mutants selected from industrial yeast strains. Auxotrophic mutants were screened by a replica plating method. After exposure to UV, colonies grown on YPD medium plates (200 to 500 per plate) were replica plated on MM and YPD medium plates, and cells that failed to grow on MM were selected.

It is used to compare the growth of the same colonies on different plates of media to determine which environments the bacterial colony can or cannot grow in (this gives insight to possible auxotrophic characteristics.

Mutant Fruit Fly Fruit flies have a very simple genetic structure, which makes them ideal for genetic research. It is useful to study mutant fruit flies, as their quick reproduction rate allows scientists to observe the advantages and disadvantages of certain mutations.

En Español. A point mutation is when a single base pair is altered. Point mutations can have one of three effects. First, the base substitution can be a silent mutation where the altered codon corresponds to the same amino acid.

They can happen spontaneously when copying errors occur during cell division. Mutations can also be induced by environmental factors, or mutagens. Examples would be exposure to chemicals or radiation. Environmental factors may have an influence on the rate of mutation, but they do not control what the mutation will be.

Answer: Somatic mutations are acquired through exposure to mutagens in somatic cells of the body. They will not be inherited unless a similar damage has happened in eggs or sperms due to the same exposure to mutagen, In that case, progeny might show the mutation.
