The correct Answer is:
To solve the question "AUG is", we will analyze each option provided and determine which one correctly describes AUG. ### Step-by-step Solution: 1. **Understanding the Codon AUG**: - AUG is a sequence of three nucleotides (Adenine, Uracil, Guanine) in RNA. - It is known as a start codon in the genetic code. 2. **Analyzing the Options**: - **Option (a) Ople**: This does not correspond to any known codon or function in genetics. - **Option (b) Amber**: This refers to the UAG codon, which is a stop codon, not related to AUG. - **Option (c) Ochre**: This refers to the UAA codon, which is also a stop codon, not related to AUG. - **Option (d) Initiation codon**: This is a correct description of AUG, as it initiates the process of translation in protein synthesis. 3. **Conclusion**: - After analyzing all the options, we find that the only correct description of AUG is that it is an initiation codon. ### Final Answer: (d) Initiation codon ---
