Seprating fragments of dna to determine similar genes by length and charge - ️️Gel electrophorsis First step - ️️Add DNA to wells in a gel Second step - ️️Run a current through the gels Third step - ️️Smaller fragments move faster and travel farther Fourth step - ️️DNA moves...

Why do gel electrophoresis? - ️️1. To determine which organisms are most closely related. 2. To determine paternity of a child. 3. For crime scene analysis. Bands - ️️A DNA ladder usually contains a set of known DNA fragments with different sizes in base pairs (bp) or kilobases (kb). Th...

What purpose does the buffer serve in gel electrophoresis? - ️️It maintains pH (at 7 which is neutral) and conducts electricity which allows the DNA fragments to migrate through the agarose gel What does "phoresis" mean? - ️️To transmit (move location, migrate) What three gel ingre...

What would you expect to happen if you left the gel accidentally in the gel electrophoresis chamber for too long? - ️️the DNA strands would not stop they would continue to move through the gel into the buffer In what situation do scientists need to use the PCR reaction? - ️️to amplify a ...

more resistance - ️️What longer strands encounter to make them move slower through the gel so that they stay closer to the wells targeting a gene with a mutation - ️️Gel electrophoresis can be used for agarose or polyacrylamide - ️️What the gel tray is made of negative - ️️the ch...
