Mysteries that can be solved by DNA•Crimes (murder, rape, robbery, etc.)•Human Identification•Prove Kinship (paternity, maternity, etc..•Prove innocence•Genetic disorders•Historical mysteries•Evolution trends
By comparing DNA fingerprints of the unknown to the known
Samples are created by gel electrophoresis
also called DNA testing, DNA typing, or DNA profiling
is a technique used to distinguish between individuals of the same species using only
samples of their DNA
Using a lysis solution and a warm water bath
Using an ultracentrifuge(separated based on density)
Using forms of alcohol to clumpDNA
Process of removing DNA from cells received from samples of blood, skin, semen, etc.
piece of equipment, generally driven by a motor, that puts
an object in rotation around a fixed axis
The centrifuge works using the sedimentation principle
where the centripetal acceleration is used to separate substances of
greater and lesser density
Process in which DNA is “cut” by restriction enzymes into fragments
Restriction Enzymes are enzymes that cut DNA at SPECIFIC sequences of nucleotides.
is a technique used for the separation of DNA, RNA, or protein molecules using an
electric current applied to a gel matrix, based
on their size and electriccharge
Gel electrophoresis
gel animation
• To determine differences in the genomes of different plant and animal species
• The number and positions of the bands formed on each lane of gel is the actual DNAfingerprint and is unique to each person
Using your notes and your knowledge of DNA fingerprinting, make a list of materials
and tools needed for us to perform a paternity test?
