Gel Electrophoresis Review: Questions And Solutions

Gel electrophoresis Right Ans - A technique used to separate segments of
DNA based on their size using an electric current

Wells Right Ans - The spaces that are loaded with DNA samples

Restriction Enzyme Right Ans - Cuts DNA molecules at a specific sequence
of nucleotides to make smaller fragments

Negative Right Ans - The charge on DNA, and electrode at the end where
the wells are

Positive Right Ans - The electrode that the DNA migrates towards

Longer DNA fragments Right Ans - Move slower through the gel and end up
closer to the wells than shorter DNA fragments

Shorter DNA fragments Right Ans - Move slower through the gel and end
up further from the wells than longer DNA fragments

Bands Right Ans - DNA fragments of the same length on the gel produce
visible

DNA ladder Right Ans - set of known DNA fragments with different sizes in
base pairs or kilo bases. these DNA fragments are separated and visualized as
DNA bands on a gel. used to determine the size and quantity of DNA fragments

DNA fingerprint Right Ans - Unique sequence of DNA base pairs that can be
used to identify a person at the molecular level

forensic science Right Ans - scientific study of crime scene evidence
the scientific analysis of evidence for crime scene and other investigations
