A portion of alcohol dehydrogenase enzyme contains 375 amino acids. Including both amino acid and all other necessary codes, how long is the coding portion of the corresponding mRNA?
Thanks
One codon is composed of three amino acids, so the coding region would be 375 divided by 3. Your welcome:)
I'm sorry, MULTIPLIED by 3
Sorry, one codon is composed of three nucleotides that code for one amino acid. Therefore, a protein of 375 amino acids would have a coding region on the mRNA strand with 375*3 nucleotides.
To determine the length of the coding portion of the corresponding mRNA, you need to understand the process of translation, which involves the conversion of the genetic code on DNA into mRNA. Here's how you can calculate it step by step:
1. Start with the number of amino acids in the protein sequence. In this case, the enzyme has 375 amino acids.
2. Each amino acid is specified by a codon, which consists of three nucleotides (bases) on the mRNA molecule.
3. Therefore, to find the length of the coding portion of the mRNA, multiply the number of amino acids by 3 (since each codon has three nucleotides).
4. Calculate: 375 amino acids x 3 nucleotides = 1125 nucleotides.
Hence, the coding portion of the corresponding mRNA for the alcohol dehydrogenase enzyme would be 1125 nucleotides long.
