2. the process of figuring out the correct order of
the four nitrogen-containing bases: Adenine,
Guanine, Cytosine, and Thymine in a section of
DNA
Sections of DNA are separated by size,
recreating the original piece of DNA
3. Established by Fred Sanger in 1977
When DNA is being replicated and a dideoxy
base is associated into a new chain, it stops the
replication reaction
4. A primer is annealed to a single-stranded
section of DNA
5. DNA- primer mixture is put into 4 separate
tubes with DNA polymerase and a solution of
dNTPs at a concentration of 100 times lower
than the dNTP concentration
7. ddNTPs are put together randomly, resulting
in different lengths of fragments
8. Fragments that are from each of the reactions
are denatured and separated by size using gel
electrophroesis
9. The gel is used to visually detect the DNA fragments.
The fragments are to be read from bottom to top and
this represents the complementary sequence of the
original strand of DNA.
10. Allows scientists to Provides details about
determine genome individuals and their
sequence families
Identify the genes Police have DNA
causing genetic samples of people that
diseases have committed no
crime
11. Too expensive
Religious beliefs
Diagnosing a genetic disorder before we have
the science to treat it causes distress in patients
12. Forensics
Identify individuals
Determine the paternity of a child
Identifies endangered and protected species
Medicine
Detect genes that are hereditary or cause diseases
Agriculture
Map the genome of microorganisms
13. Projects might focus on researching:
The links to develop lifestyle
Genomic and cardiovascular disease
Early detections of cancer
