2. Objectives
 identify all the approximately 20,000-25,000 genes in
human DNA

pairs that make up human DNA and store this
information in databases

may arise from the project

3. On January 1989 biologist and scientists
gathered and Zinder Norton declared “today
we are initiating an unending study of human
biology whatever else happen it will be an
adventure , priceless endeavor”
The main aim of human genome project is
to map the human genome.
About 3 billion nucleotide pairs encode all
human traits .

4.  It should be noted that through the first eight years of the
project ,only three percent of the human genome had
been sequenced.
 James d Watson was one of the early supporters of the
human genome initiative and the first director of the center

16. Determining the
Sequence of DNA
 Methods:
1. Chain termination or dideoxy method
 F. Sanger
2. Shotgun sequence method
3. 2nd generation sequence methods
 Pyrosequencing

17. Dideoxy (Sanger)
Method

18. • ddNTP- 2’,3’-dideoxynucleotide
• No 3’ hydroxyl
• Terminates chain when incorporated
• Add enough so each ddNTP is randomly and
completely incorporated at each base

19. Automated Version of the
Dideoxy Method

20. Shotgun sequence method
 The shotgun phase of the Human Genome Project
itself consisted of three steps:
 1-Obtaining a DNA clone to sequence
 2-Sequencing the DNA clone
 3-Assembling sequence data from multiple clones to
determine overlap and establish a contiguous
sequence

22. 2nd Generation:
Pyrosequencing
 1st generation -- chain termination
(Sanger) method
 2nd generation -- detection of PPi
(pyrosequencing = 454
sequencing)

24. 3rd generation (“next generation”) --
real-time detection of polymerization with fluorescent dNTPs

26. What are the outcomes
of The human Genome
Project?
 Genetically proven to have the ability to locate genes
that are responsible for locating diseases
 Gene Therapy used today
 The HGP has been very successful

27. Benefits/advantages
 The human genome project has
been described as the most
important experiment in the
biological sciences, providing
benefits in various fields.

28. Medicine application
 Improved diagnosis of disease
 Earlier detection of genetic
predispositions to disease
 Rational drug design
 Gene therapy and control systems
for drugs
 Pharmacogenomics "custom
drugs“

31. Energy and Environmental Applications:-
 Use microbial genomics research to create new energy
sources (biofuels)
 Use microbial genomics research to develop
environmental monitoring techniques to detect
pollutants
 Use microbial genomics research for safe, efficient
environmental remediation
 Use microbial genomics research for carbon
sequestration

32. Risk Assessment: -
 Assess health damage and risks caused by radiation
exposure, including low-dose exposures
 Assess health damage and risks caused by exposure to
mutagenic chemicals and cancer-causing toxins
 Reduce the likelihood of heritable mutations
