Which of the following is not a termination codon?
Question
Which of the following is not a termination codon?
Solution
To determine which of the following is not a termination codon, we need to first understand what termination codons are. Termination codons, also known as stop codons, are specific sequences of nucleotides in the genetic code that signal the end of protein synthesis. In most organisms, there are three termination codons: UAA, UAG, and UGA.
Now, let's examine the options provided and identify the termination codons among them:
Option 1: UAA - This is a termination codon.
Option 2: AUG - This is not a termination codon. It is actually the start codon, which signals the beginning of protein synthesis.
Option 3: UAG - This is a termination codon.
Option 4: UGA - This is a termination codon.
Based on our analysis, option 2 (AUG) is not a termination codon.
