R: Each restriction enzyme recognises a specific palindromic nucleotide sequence in the DNA.
  • a)
    If both Assertion & Reason are true, and the reason is the correct explanation of the assertion.
  • b)
    If both Assertion & Reason are true, but the reason is not the correct explanation of the assertion, then mark
  • c)
    If the Assertion is a true statement, but Reason is false.

Explanation:

Assertion: Restriction enzymes belong to a larger class of enzymes called nucleases.

Reason: Each restriction enzyme recognises a specific palindromic nucleotide sequence in the DNA.
- Restriction Enzymes: These enzymes are a type of nuclease that cuts DNA at specific recognition sites. They are commonly found in bacteria as a defense mechanism against foreign DNA.
- Nucleases: Nucleases are enzymes that cleave the phosphodiester bond between nucleotides in nucleic acids. They can be classified into different types based on their function, such as endonucleases and exonucleases.
- Specific Palindromic Sequence: Each restriction enzyme recognizes a specific sequence of nucleotides in DNA, known as a recognition site. These recognition sites are often palindromic, meaning they read the same forward and backward.
- Correct Explanation: The reason provided correctly explains the assertion. Restriction enzymes are a specific type of nuclease that recognize palindromic sequences in DNA to cleave the DNA at specific sites. This specificity is essential for their function in genetic engineering and molecular biology applications.
Therefore, option 'B' is the correct answer as both the assertion and reason are true, and the reason correctly explains the assertion.
