Locating and sequencing genes. DNA probes. Used to locate a specific gene sequence / gene A short, single stranded section of DNA… Labeled with… What do you think a probe could be labeled with?
Short fragments of DNA
Increasing distance from the origin
Long fragments of DNA
Explains the process nicely.
Does not explain the process very well but shows how you arrive at the final sequence.
Possible gel electrophoresis results of 3 different restriction mapping “double digests”
The numbers are the lengths of the fragments produced by the enzymes in kilobases
Video shows how to use the results of restriction mapping.
