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
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
A primer is annealed to a single-stranded section of DNA
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
ddNTPs are put together randomly, resulting in different lengths of fragments
Fragments that are from each of the reactions are denatured and separated by size using gel electrophroesis
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.
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
Too expensive Religious beliefs Diagnosing a genetic disorder before we have the science to treat it causes distress in patients
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
Projects might focus on researching: The links to develop lifestyle Genomic and cardiovascular disease Early detections of cancer
