3
Definition of DNA

• DNA ( deoxyribonucleic acid )
• a polynucleotide having a specific sequence
  of deoxyribonucleotide units serves as the
  carrier of genetic information .

4
DNA structure

• Nitrogen bases.
• Deoxyribose sugar.
• Phosphate group.

5
Characteristics of DNA

• Replication.
• Storage of information.
• Expression of information.
• Variation by mutation .

6
Disorder of DNA result from

• Single mutation.

• Specific chromosomal abnormality.

7
For example

• Down syndrome.

• Sickle-cell anemia.

8
Methods of treatment

• Blood transfusions.
• Organ transplant.

9
Future expectations

• Identification of new genes.
• Correct genetic defects
• Improve the agriculture.

10
Ways of agricultural improvements

• Enhance potential for more vigorous growth.
• Increase resistance to natural predators.
• Production of hybrids exhibiting a combination of
  superior traits derived from two different
  strains.

11
Disadvantage of modified food

• It may harm our health because they had little
  time for research on long-term medical and
  ecological effects on modified foods .

12
Conclusion

• The discovery of DNA structure help people to
  diagnose the genetic disease and help the society
  in the agricultural fields .
