This is the last step of PCR and it requires the temperature to increase to 72C for one minute. Here, complementary strands will be produced from the corresponding base pairs, reforming the DNA into two new strands.

• Elongation by DNA Polymerase

• Primer Annealing

• Denaturation

Why are restriction enzymes used when making a DNA fingerprint using STRs?

• They are used to determine the size and shape of DNA fragments.

• They are used in order to allow us to determine if a specific family or family member is related to the crime based on their DNA fragments.

• STR bands are units of bases that are typically two to five bases long and repeat multiple times. Restriction enzymes cut these bands since they match the enzyme, making them easily recognisable.
