The start and stop codons are? (Farm Manager 2017)

✅Explanation:
-AUG: Start codon signaling protein synthesis initiation.
-UAG: One of three stop codons signaling protein synthesis termination.
📌 Other Options Explanations
-(b) AUU and UAA: AUU codes for Isoleucine; UAA is a stop codon.
-(c) AAG and UGA: AAG codes for Lysine; UGA is a stop codon.
-(d) AUG and UGG: AUG is the start codon; UGG codes for Tryptophan.

🔑Key Points:
Codon Functions
-Start Codon: AUG (also codes for Methionine).
-Stop Codons (Nonsense Codons): UAG (Amber), UAA (Ochre), UGA (Opal); encode no amino acid.

✏️Specific Codons:
-UGG: Tryptophan.
-UGC: Cysteine.
-UAC: Tyrosine.
