Question

Indicate whether the following statements about DNA fingerprinting are true or false.1. DNA fingerprinting compares mitochondrial DNA samples. 2. DNA fingerprinting compares X chromosomes. 3. DNA fingerprinting decreases the necessary sample size.4. DNA fingerprinting increases the amount of evidence.5. DNA fingerprinting compares Y chromosomes.

Answer 1

DNA fingerprinting

Explanation:

• DNA fingerprinting compares mitochondrial DNA samples."True" statement because this technique is used for analysis of paternity cases by the forensic scientist to examine the child's DNA with parents.
• DNA fingerprinting compares X chromosomes. "False" statement because technique is used for DNA and Y chromosomes loci not for compare the x chromosome.
• DNA fingerprinting decreases the necessary sample size. "true" statement this is because through the use of this tecnique DNA sample is decrease due to the use of PCR, RFLP, methods it will be divided into small fragments.
• DNA fingerprinting increase the amount of evidences. "False" statement because this technique decrease the amount of sample as discuss in step 3 of the answer.
• Dna fingerprinting compares Y chromosomes. "True"  statement because in DNA databases this technique is used to locate the y chromosome loci. to identify the segment of DNA
• Hence, the answer is "True,false,True,false,True".

Answer 2

Answer:

TRUE DNA fingerprinting compares mitochondrial DNA samples.

FALSE DNA fingerprinting compares X chromosomes.

TRUE DNA fingerprinting decreases the necessary sample size.

FALSE DNA fingerprinting increases the amount of evidence.

TRUE DNA fingerprinting compares Y chromosomes.
