Question

identifying types of dna technology
identify which form of dna analysis is described.
it analyzes genetic markers that are passed from father to son.
the fbi utilizes these for their database.
it is used when other forms of dna analysis are not possible because it does not rely on nuclear dna.
it allows a small amount of dna to be duplicated into a testing amount.

Explanation:

1. Y - chromosome analysis examines genetic markers passed from father - to - son as the Y - chromosome is male - specific.
2. Short tandem repeat (STR) analysis is used by the FBI for its database due to its ability to identify individuals accurately.
3. Mitochondrial DNA analysis is used when nuclear DNA analysis is not possible as mitochondria have their own DNA.
4. Polymerase chain reaction (PCR) can duplicate a small amount of DNA into a larger, testable amount.

Answer:

1. Y - chromosome analysis
2. Short tandem repeat (STR) analysis
3. Mitochondrial DNA analysis
4. Polymerase chain reaction (PCR)
