A: Triplet genetic code can be confirmed by frame shift mutations.
R : Frame shifting involves the change in protein product coded by triplet codons.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark
B. If both Assertion & Reason are true and the reason is not the correct explanation of the assertion , then mark
C. If Assertion is ture statement but Reason is false, then mark.
D. If both Assertion and Reason are false statements, then mark.

Answer

To analyze the assertion and reason provided in the question, we will break down the concepts step by step.

### Step 1: Understanding the Assertion
**Assertion (A):** "Triplet genetic code can be confirmed by frame shift mutations."
- The triplet genetic code refers to the way in which sequences of three nucleotides (codons) in DNA or RNA correspond to specific amino acids in proteins.
- Frame shift mutations occur when nucleotides are inserted or deleted from the DNA sequence in a number that is not a multiple of three. This shifts the reading frame of the codons.

### Step 2: Understanding the Reason
**Reason (R):** "Frame shifting involves the change in protein product coded by triplet codons."
- Frame shift mutations alter the grouping of nucleotides into codons.
- This alteration can lead to the production of entirely different amino acids and hence a different protein product than what was originally intended.

### Step 3: Evaluating the Truth of Assertion and Reason
- Both the assertion and the reason are true. The triplet nature of the genetic code can indeed be confirmed through the effects of frame shift mutations. When the reading frame is altered, the resulting protein product changes, confirming the triplet nature of codons.

### Step 4: Determining if Reason is the Correct Explanation of Assertion
- The reason provided does correctly explain the assertion. Frame shift mutations demonstrate how the triplet code works by showing the consequences of altering the reading frame, which directly affects the protein product.

### Conclusion
- Both the assertion and reason are true, and the reason is the correct explanation of the assertion.

### Final Answer
**Assertion (A)** is true, **Reason (R)** is true, and **Reason (R)** is the correct explanation of **Assertion (A)**.
