TMA COC ACT. She says that she wrote the mRNA as ATT GCG TGA, but now she's not sure how to use the codon table above to figure out the amino acids.

Part 2: Using the codon table along with the correct nucleotide sequence, teach JaNeya how to use the codon chart. Make sure you include each step as well as the final amino acid sequence in your explanation.

Sagot :

Sure, Jameya! Let’s work through this step-by-step to find the amino acid sequence from the mRNA sequence you’ve provided. The sequence you gave is "ATT GCG TGA". First, let me correct that this question seems to have some transcription errors in the table and text as there are gibberish words such as 'A. o' and mismatched symbols (e.g., '[tex]$u$[/tex]', '(Stat)').

Assuming the correct format for the codon table based on typical codon charts, let’s proceed to find the amino acids.

1. Separate the mRNA sequence into codons:
The given mRNA sequence is "ATT GCG TGA". Breaking it down into codons, we have:
[tex]\[ \text{ATT, GCG, TGA} \][/tex]

2. Use the codon chart to translate each codon into an amino acid:

Let’s look up each codon in the codon table:

- For the codon "ATT":
- First base: A
- Second base: U
- Third base: T

According to a typical codon chart (if looking at a properly typed one), for "A U*-T":
[tex]\[ \text{Look under A row and U column} \][/tex]
- Using the table provided, determine the correct amino acid.

- For the codon "GCG":
- First base: G
- Second base: C
- Third base: G

According to a typical codon chart:
- Using the table provided for "G C*-G":
[tex]\[ \text{Look under G row and C column, then G entry} \][/tex]

- For the codon "TGA":
- First base: T (U in RNA)
- Second base: G
- Third base: A

According to a typical codon chart:
- Using the chart and map rows and columns properly for "T* G-A":
[tex]\[ \text{Check for possible translation (Stop codons often)} \][/tex]

Here, correcting errors in the explanation and proper column readings is advised.

So, the correct amino acids derived step by step from correct practices would show specific matches.

Since we don't have correct alignment on all rows (which might mean transcription or OCR errors), typical lookup examples:
[tex]\[ \text{ATT would map potentially to Ile, GCG to Ala, TGA often Stop.} \][/tex]
Verifying each mapping:
1. Att: Ile
2. GCG: Ala
3. TGA: Stop codon
Thus likely produced:
[tex]\[ \text{ sequence ends up: [Ile]-[Ala]-[Stop].} \][/tex]

Important Step:
Every codon-triplet mapped correctly gives functionally correct proteins, ensuring care or use validated codon charts for map. Typically, resources and biology codon charts ensure exact correspondence.

So, to conclude, after perfect reading the mRNA sequence "ATT GCG TGA" translates to ["Isoleucine", "Alanine", "Stop"] as amino acids. Ensure tables are cross-checked and discussed values properly studied.
Great for further science explorations!
