Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion : DNA finger p rin tin g is a method in which polymerase chain reaction followed by DNA probe is used.
Reason: A DNA fingerprint is inherited and therefore, resembles that of parents.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.
  • e)
    Both Assertion and Reason are false.
Correct answer is option 'B'. Can you explain this answer?

Directions: In the following questions, a statement of assertion (A) ...
DNA fingerprinting is also called DNA profiling. It is a laboratory technique used to identify the individuals with the characteristics of their DNA. It is used to solve some crime mysteries like murder, rape etc. Usually, the samples (e.g., blood, semen,saliva) that are available for the testing are small. Hence, polymerase chain reaction is used to amplify the amount of DNA present in the sample. Hence, the assertion is correct.
DNA fingerprints have an inheritable quality. The pattern types of the DNA fingerprints are often genetically inherited from the parents to the offsprings. Hence, the DNA fingerprint resembles that of parents. The reason is correct but it is not a correct explanation of the assertion. Thus, the correct answer is option B.

Directions: In the following questions, a statement of assertion (A) ...
Assertion: DNA fingerprinting is a method in which polymerase chain reaction followed by DNA probe is used.

Reason: A DNA fingerprint is inherited and therefore, resembles that of parents.

The correct answer is option 'B': Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

Explanation:

DNA fingerprinting, also known as DNA profiling or DNA typing, is a technique used to identify individuals based on their unique DNA patterns. It involves the analysis of specific regions of the DNA that are highly variable among individuals.

Reason Explained:
The reason provided in the statement is that a DNA fingerprint is inherited and therefore, resembles that of parents. However, this reason does not explain why polymerase chain reaction (PCR) followed by DNA probe is used in DNA fingerprinting.

Explanation of Assertion:
DNA fingerprinting involves multiple steps, and PCR followed by DNA probe is one of the key steps in this process. PCR is a technique used to amplify a specific region of DNA, making it possible to obtain sufficient DNA for further analysis. In DNA fingerprinting, PCR is used to amplify specific regions of the DNA that contain variable number tandem repeats (VNTRs) or short tandem repeats (STRs). These regions have a high degree of polymorphism among individuals, allowing for the differentiation of individuals based on their DNA patterns.

After PCR amplification, DNA probes are used to detect and analyze the amplified DNA fragments. These probes are short sequences of DNA that are complementary to the VNTR or STR regions. They can bind specifically to the amplified DNA fragments, allowing for their detection and analysis.

Conclusion:
In conclusion, the assertion that DNA fingerprinting involves the use of PCR followed by DNA probe is true. However, the reason provided is not the correct explanation for this assertion. The reason suggests that DNA fingerprinting is based on the inheritance of DNA patterns from parents, but it does not explain why PCR and DNA probe are specifically used in this technique.
