The correct Answer is:
To analyze the given assertion and reason, let's break it down step by step. ### Step 1: Understand the Assertion The assertion states: "Normally the genetic code is degenerate." - The term "degenerate" in genetics refers to the fact that multiple codons can code for the same amino acid. This means that the genetic code is not unique; rather, there are redundancies. ### Step 2: Evaluate the Assertion - While it is true that many amino acids are coded by more than one codon, the assertion uses the word "normally," which implies that this is a general rule for all genetic codes. However, there are exceptions where certain amino acids are coded by only one codon (e.g., Methionine and Tryptophan). Therefore, the assertion is misleading. ### Step 3: Understand the Reason The reason states: "One amino acid is coded by more than one codon." - This statement is true as it reflects the characteristic of the genetic code where many amino acids are indeed specified by multiple codons. ### Step 4: Evaluate the Reason - While the reason is true, it does not justify the assertion because the assertion is incorrectly generalized. The reason applies to some amino acids but not all. ### Step 5: Conclusion - Since the assertion is false and the reason is true but does not explain the assertion, we conclude that: - Assertion: False - Reason: True ### Final Answer Both assertion and reason are false.
