This image contains a sequence of DNA nucleotides from the 5' to 3' direction: 

**5' CTATAAGGGCGCAAATCCCTGCCAT 3'**

Within this sequence, specific nucleotides are highlighted and labeled:

1. A blue arrow labeled "1" points to a **C** nucleotide.
2. A red arrow labeled "2" points to a **C** nucleotide.
3. A purple arrow labeled "3" points to a **G** nucleotide.
4. A green arrow labeled "4" points to a **G** nucleotide.

The colored arrows and numbers denote specific positions or features in the DNA sequence that may be of interest for educational or analytical purposes.

The colored arrows and numbers denote specific positions or features in the DNA sequence that may be of interest for educational or analytical purposes.
The image displays a codon chart, which is a key tool used in molecular biology to understand the genetic code. It helps in translating nucleotide sequences into amino acids, the building blocks of proteins.

### Structure of the Codon Chart:

- **Reading the Chart**: The chart is organized based on three positions (first, second, and third bases) corresponding to the RNA codon sequences.

- **First Base**: Listed vertically on the left side of the chart. Includes the bases Uracil (U), Cytosine (C), Adenine (A), and Guanine (G).

- **Second Base**: Indicated at the top, horizontally. Also includes the bases U, C, A, and G.

- **Third Base**: Listed vertically on the right side of the chart. Same bases as the first.

### Interpretation of Codons:

- Each combination of the first, second, and third bases results in a specific amino acid or a stop signal. 

- **Examples**:
  - UUU or UUC codes for Phenylalanine (F).
  - AUG codes for Methionine (M), which is also the start codon.
  - UAA, UAG, and UGA are stop codons, signaling the end of protein synthesis.

- The amino acids and stop signals are written at the intersection of the respective bases.

### Amino Acids:

- Abbreviated with both three-letter and one-letter codes.
- For instance, Serine is indicated as Ser (S), and Glutamate as Glu (E).

### Purpose of the Codon Chart:

- Helps in gene expression studies and in understanding mutations that can affect protein synthesis.
- Important for researchers and students in genetics, molecular biology, and related fields.

This chart serves as a fundamental resource in genetics to decode the sequences of mRNA into functional proteins.
