DNA Mutation
Any change in DNA molecule results in
permenent alteration in the base
sequence in daughter DNA.
causes:
Uncorrected errors
Damage by (oxidative deamination,
radiation & chemicals)
Types
A.
Point mutation
B.
Insertion mutation
C.
Deletion mutation
D.
Frameshift mutation
E.
Lethal mutation
DNA mutations are changes in the DNA molecule that can lead to permanent alterations in the base sequence of daughter DNA. Causes include uncorrected errors, as well as damage from oxidative deamination, radiation, and chemicals. The types of mutations include point mutations, insertion mutations, deletion mutations, frameshift mutations, and lethal mutations. Explore the complexities of DNA mutations in this informative content.
