MUTATION

TYPES OF MUTATION

WHAT IS MUTATION?

WHAT IS MUTATION?-Genes can be alerted to do unexpected and random changes called mutatuons.-Mutation is a natural process that changes a DNA sequence.-Mutations CAN BE HARMFUL to individuals

-GENE MUTATION: affects the chemical structure of the DNA-CHROMOSOME MUTATION: affects the structure of the chromosome-NUMERICAL MUTATION: affects the number of chromosomes

SUBTYPES

There are lots of SUBTYPES such as -AUTOSOMAL DISORDERS: Down, Edwards, Patau syndrome-CHANGES IN CHROMOSOME STRUCTURE:Deletion, Duplication, Inversion, Translocation

-DOWN SYNDROM(below)

-PATAU SYNDROME(below)

-EDWARDS SYNDROME(below)

CAUSES OF MUTATION

-PHYSICAL MUTAGENS is when Radiation causes damage to the genetic material-CHEMICAL MUTAGENS is when pesticides or pollution causes change in the genetic material-BIOLOGICAL MUTAGENS is when some viruses increase the frequency of genetic mutation.

PHYSICAL MUTAGENS

- X-rays, Radiation from radioactive processes and Sun rays are the ones creating the damage.-Scientists have proven that a large number of species form the Radioactive city of CHERNOBYL possess large TUMORS and PHYSICAL ABNORMALITYS due to the radiation.
