DNA fingerprinting Flashcards
1
Q
definition of DNA fingerprinting
A
representation of individuals DNA that can b e used to identify someone at the molecular level
2
Q
how does it work
A
cut up DNA with restriction enzymes at known locations
2- run through gelelectrophoresis
3- see the bands -the more repeats in the DNA, the larger the DNA strand is and the closest to the wells to band will be
3
Q
what it shows
A
the length of DNA fragmenrs between restriction sites
differences in # of repeats in non coding region
4
Q
what is it based on
A
the # of repeeats on the noncoding region of the DNA sequence
