2. Aim #42: How do scientists use biotechnology to manipulate genomes?

3. 1) What is biotechnology?
The use of organisms to perform practical tasks for
humans.
Bacteria, help us
make yogurt & cheese.
Yeast, helps us
make bread & wine.

4. 2) What is a genome? Complete set of an organism’s genetic material.
The Chromosomes, DNA, & the
Genes which are all found in the
Nucleus.

5. 3) What is a Gene? A gene is a sequence of DNA on a chromosome that
codes for ________ protein.
one

6. 4) What is DNA Technology?
The branch of biotechnology where scientists actually
manipulate (alter) the genomes of organisms at the
molecular level.

7. 5) Why would altering DNA affect our characteristics/traits?
DNA codes for the proteins that determine our traits.

8. 6) What are some examples of DNA Technology?
Cloning
DNA Fingerprinting
Recombinant
DNA
GMO

9. 7) Scientists often use bacteria & viruses in DNA Technology
How do bacteria reproduce?
Asexual Reproduction
Does that lead to variation in
offspring?
No, it leads to clones

10. 8) Human Genome Project:
In 1990, advances in DNA technology enabled
scientists to completely sequence the human genome.
A rough draft was complete
in 2000.

11. 9) Steps of the Human Genome Project:
Sequence the DNA (order of the bases).
Regions of DNA that code for proteins (genes) must
be distinguished from non-coding regions.
3) The functions of the resulting proteins must be
determined.
4) Develop a map of the human genome.

12. Human Genome Project
Scientists studied and mapped the human genome (determined the entire nucleotide sequence of DNA).

13. Why is this so important?
Comparing human sequences with those from other species provide insight into evolutionary relationships.
Identifying genes will aid in diagnosing, treating,& preventing common ailments.
