Question

biology nord ic qtr b continuous learning center - credit bearing (tutor) applications of dna technology reviewing dna fingerprinting indicate whether these statements about dna fingerprinting are true or false. dna fingerprinting compares mitochondrial dna samples. dna fingerprinting compares x chromosomes. dna fingerprinting decreases the necessary sample size. dna fingerprinting increases the amount of evidence. dna fingerprinting compares y chromosomes. assignment 4 of 11 submit

Explanation:

1. DNA fingerprinting often compares nuclear DNA, not just mitochondrial DNA. So, "DNA fingerprinting compares mitochondrial DNA samples" is false.
2. DNA fingerprinting doesn't specifically compare X - chromosomes. It looks at variable regions in the genome. So, "DNA fingerprinting compares X chromosomes" is false.
3. DNA fingerprinting is sensitive and can work with small sample sizes, but it doesn't decrease the necessary sample size in the sense of changing the fundamental requirements. It can analyze small amounts well. So, "DNA fingerprinting decreases the necessary sample size" is false.
4. DNA fingerprinting provides unique genetic information which can increase the amount of evidence in cases like criminal investigations or identification. So, "DNA fingerprinting increases the amount of evidence" is true.
5. DNA fingerprinting doesn't specifically compare Y - chromosomes only. It examines multiple regions. So, "DNA fingerprinting compares Y chromosomes" is false.

Answer:

1. False
2. False
3. False
4. True
5. False
