Question

Fill in the table &Classification of gene mutations &:

Classification of gene mutations according to

Occurrence 

Gene localization

Phenotype manifestation

Cell localisation 

Organism localisation

By mechanisms of occurrence

Answer 1

Occurrence: Gene mutations occur at some time during a person’s life and are present only in particular cells. Gene mutation does not occur in every cell. The changes are caused by environmental factors such as ultraviolet radiation.

Gene localization: This is the process through which a cellular entity such as a protein complex is transported or maintained to a specific location.Classification of gene mutations according to

Phenotype manifestation: It is the manifestation of multiple traits resulting from several genetic variants.

 

Cell localization: This is the process through which a gene is transported and maintained in a specific location within the cell membrane.

Organism localization: This is the process through which organelle is transported and tethered to a specific location that can be achieved via selective degradation.

By mechanisms of occurrence: Gene mutation can occur spontaneously owing to several mechanisms such as DNA error replication and DNA damage.
