Which was used o copy DNA for DNA figerprinting

First, we use the polymerase chain reaction (PCR) technique to copy a tiny fragment of DNA so that there is enough to use in gel electrophoresis. Gel electrophoresis uses gel and electricity to separate DNA fragments based on size, creating a distinct pattern that represents an individuals genetic information

Explanation:

Warm Front. A warm front is the surface boundary between a warm air mass and a cold air mass it is overtaking The warm air moves into an area of colder drier air The air masses do not readily mix therefore the warm air rises slowly over the colder air because it is less dense.
