Question

Below is a section of DNA (210 consecutive base pairs of DNA) that includes only the beginning of the sequence of gene OMG1. The underlined sequence (from position 20-54) represents the promoter for gene OMG1 the underlined and italicized sequence (from position 71-90) encodes the gene OMG1 ribosome binding site (RBS). Transcription begins at and includes the T/A base pair at position 60 (bold) Codon table can be found at the end of this question A. What are the first 6 nucleotides of the mRNA from gene OMG1? B. What are the first 4 amino acids encoded by gene OMG1?

Explanation / Answer

A) ATTTGC are the first six nucleotides of the mRNA from gene OMG1

B)The first four nucleotides encoded by the gene OMG1 is GTCC

The first four amino acids are 1. Valine- encoded by GTC (Val/V)

2. Serine- encoded by TCC (Ser/S)

3. Proline- encoded by CCG (Pro/P)

4. Arginine- Encoded by CGT (Arg/R)
