Avery and DNA

This scientist discovered that DNA was the transforming principal by destroying different parts of the bacteria until a mouse lived and the R strain didn't transform into S.

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.

Which of these is NOT a difference between DNA and RNA?

• DNA uses deoxyribose in its backbone and RNA uses Ribose
