The correct Answer is:
To determine how many stop codons are present in the genetic code, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Genetic Code**: The genetic code consists of codons, which are sequences of three nucleotides that correspond to specific amino acids or signals during protein synthesis. 2. **Total Codons**: There are a total of 64 codons in the genetic code. This includes both codons that code for amino acids and those that serve as stop signals. 3. **Identify Stop Codons**: Among these 64 codons, there are specific codons that do not code for any amino acid but instead signal the termination of protein synthesis. These are known as stop codons. 4. **Count the Stop Codons**: There are three specific codons that function as stop codons: - UAA - UAG - UGA 5. **Conclusion**: Therefore, the total number of stop codons in the genetic code is 3. ### Final Answer: There are **3 stop codons** in the genetic code. ---
