Question

List the spontaneous vs environmentally natural causes of mutation discussed in lecture, their source (i.e. how
they occur/where they came from) and their specific effect on the DNA.

Answer 1

Answer:

Spontaneous mutation	Environmentally natural cause (Induced mutation)
Mutation caused by abnormal cell function. It is naturally occurs.	It is caused by some chemical or physical agents (also called as mutagens)that is used for any treatment and this leads to change in the DNA of the living organisms (mutation)
Replication error, transposable elements depurination and deamination	Mainly occurs due to base mispairing, base damages etc
It is important factor in forward genetics	It is important in reverse genetics
Insertion, deletion, duplication or translocation takes place	Transition, transversion and also frame shift mutation can occur by deleting or adding nucleotides in the base pair
