Transcript and Presenter's Notes

Title: Biotechnology


1
Biotechnology Genomics
2
DNA Cloning
  • Producing identical copies through asexual means.

3
Uses
  • determine genetic differences
  • research purposes
  • ex disease mechanism, industrial uses
  • genetic modification or organisms or gene therapy
  • genetic testing / crime investigation , forensics

4
Recombinant DNA (rDNA) technology
  • Vector foreign DNA ex. Plasmid
  • Necessary to make rDNA
  • restriction enzyme sticky ends cats
    specifically
  • DNA Ligase
  • PCR, process that uses DNA polymerase

7
DNA Analysis
  • DNA fingerprinting
  • Cut DNA?unique band pattern
  • Electrophoresis used to separate DNA by size
    for analysis
  • RNA , Protein

8
DNA Fingerprinting Paternity
9
uses electrophoresis to move charged molecules
through a matrix
10
Biotechnology Products
  • some made by genetic engineering

11
Products of genetics modification procedures
  • A Transgenic bacteria uses
  • Medicines, hormones, vaccines, agriculture,
    industry to clean waste
  • B Transgenic plants
  • Assist agriculture, make products
  • C Transgenic animals
  • Transform egg cells larger / more productive
    animals
  • D Stem cell research
  • Medicinal uses

Transgenic Mammals
14
Genomic Differences BetweenChimps Humans
15
Genomics study of genes
  • Human genome project 25,000 coding genes
  • Comparing genomes much similarity therefore,
    possible uniqueness is caused by the regulation
    of our genes
  • how our bodies function, how to prevent diseases,
    what makes different species unique, and even how
    life evolved on earth.

16
Hap Map project
  • A HapMap is a catalog common sequence differences
    that occur in a species
  • The goal of the project is to link haplotypes to
    risk for specific illnesses
  • May lead to new methods of preventing,
    diagnosing, and treating disease

17
Epigenetics DNA packaging causing expression
or no expression of genes depends on the
environmental factors one is exposed to.
18
Genetic profile the human genotype of a person
To help disease risk factors.
19
Proteomics
  • Study of proteins
  • Structure function of proteins to design drugs

20
Bioinformatics
  • Using computers to study the genome

21
Gene Therapy
  • Inserting genetic material into human cells for
    the treatment of a disorder.

Study QuestionA plasmid Yip5 is cut
  • Two linear fragments of 942 and 4,599 base pairs
    (5,541 - 942 4,599). EcoRI and EagI
  • Two linear fragments of 2,003 (2,035 - 32) and
    3,538 (5,541 - 2,003) base pairs. HindIII and
    ApaI
  • Three linear fragments of 2,003, 2,881 (4,916 -
    2,035), and 657 5,541 - (2,003 2,881)l base
    pairs. HindIII, ApaI, and PvuI
  • The 942-base-pair fragment The 4,599-base-pair
    fragment would be cleaved into two fragments of
    2,305 (3,247 - 942) and 2,294 (4,599 - 2,305)
    giving 3 total fragments. EcoRI and EagI,PvuII

Construct the plasmid
24
More Study Questions
  • PCR makes gene cloning possible because it
    enables lab technicians to do what very quickly?
  • If a plasmid is cut with a restriction enzyme 3
    times how many linear fragments will it produce?
  • How will they be arranged on an electrophoresis
    gel?

25
But wait, theres more!!
  • Explain what recombinant DNA is
  • If a specific DNA code is removed from a bacteria
    and placed into another bacteria what is this
    process called?
  • Why are restriction enzymes generally used in a
    lab?
  • Dinosaur DNA has been found in very few fossils,
    scientists want to compare the dino DNA to DNA of
    reptiles, what technique will they use to
    increase the amount of dino DNA?
