What specific technique is this biotechnology used for?

Once loaded into the well, DNA will...

• move randomly throughout the agarose gel.

• be pushed away from the positive end end.

• move towards the positive electrode once an electric current is running through.

• move towards the negative electrode once an electric current is running through.

The diagram illustrates the results of electrophoresis of DNA sequences obtained from a family of two adults and three children. Results for another female (X) are included for comparison. The banding patterns of the DNA fragments reveal that

• child 1 and child 2 cannot be biological siblings

• child 1 and child 3 probably look like the mother

• the mother cannot be the biological parent of all three children

• the mother’s DNA has the same DNA sequence as the father’s DNA
