4. MUTATION IS HERITABLE CHANGES
IN THE GENETIC MATERIAL THAT
PROVIDE THE RAW MATERIAL FOR
EVOLUTION.

9. Classification OF MUTATION
There are different ways of classifying mutation
Functional Structural
Harmful Beneficial Neutral
Point
Frame shift
Silent
Missense
Nonsense

10. Beneficial Mutation
 Beneficial are the ultimate source of
genetic variation.
Raw material for evolution.
For
example,
Protection
against
HIV
infection

11. Neutral Mutation
A neutral mutation is a mutation that occurs in a
amino acid codon but it has no impact.
Wild-type AUG UUG CAG UGG UAA
TAC AAC GTC ACC ATT
M e t h - P h e n - G l n - T r p
TAC gAC GTC ACC ATT
AUG cUG CAG UGG UAA
Meth leu gln trp
A change in base pare results in an amino acid
change but the new amino acid has the same
chemical properties as the blood group.

12. Point mutation
