Question

which amino acid, if any, does the codon ugg encode?

none, ugg is a start codon.
none, ugg is a stop codon.
met (methionine)
gly (glycine)

Explanation:

Step1: Locate the codon UGG

In the codon table, find the row where the first base (5' end) is U, the second base is G, and the third base (3' end) is G.

Step2: Identify the amino acid

Looking at the table, the codon UGG corresponds to Trp (Tryptophan). Wait, but the options given don't have Trp? Wait, no, let's re - check the options. Wait, maybe I made a mistake. Wait, the options are: None, UGG is a start codon; None, UGG is a stop codon; Met (methionine); Gly (glycine). Wait, no, in the standard genetic code, UGG codes for Tryptophan. But maybe there's a mis - option? Wait, no, looking at the table provided in the image, UGG is labeled as Trp. But the options don't have Trp. Wait, maybe the user made a typo, but among the given options, none of them is correct? Wait, no, wait the start codon is AUG (Met), stop codons are UAA, UAG, UGA. UGG is Trp. But the options given: Let's re - check the options again.

Wait, the options are:

1. None. UGG is a start codon. (Incorrect, start codon is AUG)
2. None. UGG is a stop codon. (Incorrect, stop codons are UAA, UAG, UGA)
3. Met (methionine) (Incorrect, Met is AUG)
4. Gly (glycine) (Incorrect, Gly codons are GGU, GGC, GGA, GGG)

Wait, this is a problem. But according to the genetic code, UGG codes for Tryptophan. But since none of the options have Trp, but maybe there's a mistake in the options. However, based on the standard genetic code:

Start codon is AUG (codes for Met), stop codons are UAA, UAG, UGA. UGG codes for Trp. So among the given options, all are incorrect? But that can't be. Wait, maybe the table in the image has UGG as Trp, but the options are wrong. But the question is to choose from the given options. Wait, maybe I misread the table. Let me re - check the table in the image.

Looking at the table:

First position U, second position G, third position G: UGG is Trp.

The options:

• "None. UGG is a start codon." (Start codon is AUG, so wrong)
• "None. UGG is a stop codon." (Stop codons are UAA, UAG, UGA, so wrong)
• "Met (methionine)" (Met is AUG, wrong)
• "Gly (glycine)" (Gly is GGU, GGC, GGA, GGG, wrong)

But since the problem is to choose from the given options, and there's no correct option, but maybe there's[SSE Completed, Client Connection Error][SSE Completed, Client Connection Error][LLM SSE On Failure]
