**Genetic Code Chart**
The genetic code chart displayed is a table that translates RNA codons into their corresponding amino acids. It is arranged such that the first, second, and third letters in the codon determine the resultant amino acid.
- **Rows**: Structured by the first letter of the codon (U, C, A, G).
- **Columns**: Divided by the second letter of the codon within four sections.
- **Cells**: Each cell then specifies the third letter of the codon to determine the specific amino acid or stop signal.
**Codons and Amino Acids Mapping** (selected examples):
- UUU, UUC: Phenylalanine (Phe)
- AUG: Methionine (Met), serves as the start codon
- UAA, UAG, UGA: Stop codons, signal termination of protein synthesis
**Problem Description**
A mutation occurs during replication, producing a new DNA sequence: 3'-ATG-5'. The task is to determine the RNA codon transcribed from this DNA sequence and identify the corresponding amino acid using the genetic code.
To solve this, match each DNA base with its complementary RNA base:
- DNA "A" pairs with RNA "U"
- DNA "T" pairs with RNA "A"
- DNA "G" pairs with RNA "C"
This gives the RNA sequence as 5’-UAC-3’. According to the genetic code chart, the RNA codon UAC corresponds to the amino acid Tyrosine (Tyr).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdbf8765a-c0ab-46fe-8663-61e338d72b7c%2F27b3d1e8-ec77-4dd3-92a3-ce1e12e2a31b%2F076q0rh_processed.jpeg&w=3840&q=75)
