In bacteria , the codon AUG stands for

Options

A. (a) Glycine
B. (b) Methionine
C. (c) N-Formyl methionine
D. (d) Alanine

Answer

To answer the question "In bacteria, the codon AUG stands for," we will follow these steps:

### Step 1: Identify the Codon
The codon in question is AUG. Codons are sequences of three nucleotides that correspond to specific amino acids.

**Hint:** Remember that codons are made up of three nucleotides and are used in the process of translation.

### Step 2: Determine the Function of AUG
AUG is known as the start codon. It signals the beginning of protein synthesis and is crucial for initiating the translation process.

**Hint:** Think about the role of start codons in the translation process of proteins.

### Step 3: Identify the Amino Acid Coded by AUG
In bacteria, the AUG codon codes for the amino acid methionine. However, in prokaryotes (like bacteria), this methionine is modified to form N-formyl methionine (fMet).

**Hint:** Consider how the same amino acid can have different forms in prokaryotes and eukaryotes.

### Step 4: Conclusion
Therefore, in bacteria, the codon AUG stands for N-formyl methionine.

**Final Answer:** In bacteria, the codon AUG stands for N-formyl methionine.
