2.5 the use of gel electrophoresis

gel electrophoresis

a technique for sorting a mixture of DNA fragments through an electric field on the basis of different fragment lengths

DNA fingerprinting

technique for identifying DNA from different individuals based on variable numbers of tandem repeats of short DNA segments near the ends of chromosomes

DNA sequencing

identification of the order or sequence of bases along a DNA strand

agarose gel

a special type of porous gel used in gel electrophoresis, which allows for DNA to be separated by fragment size

DNA profiling

technique for identifying DNA from different individuals based on variable regions known as short tandem repeats (STRs)

short tandem repeats (STRs)

chromosomal sites where many copies of a short DNA sequence are joined end-to-end; the number of repeats is variable between unrelated people
