Question

You have discovered two different mutations of gene OMG1, mutation 1 and mutation 2. C. In mutation 1, there is an insertion of the following three base pairs immediately after the C/G base pair at position 100 (shown in bold on the DNA sequence). 5"TGT3' 3'ACA5' (i) Would the mRNA expressed from this version of gene OMG1 be longer, shorter, or the same as that produced from the normal gene OMG1? Explain and if longer or shorter, indicate by how many bases. (ii) If the mRNA can be translated, would you expect the protein to be longer, shorter, or the same as that produced from the normal gene OMG1? If longer or shorter, indicate by how many in amino acids. (iii) Do you expect the protein produced will have the same function as the normal protein OMG1? Explain your reasoning.

Explanation / Answer

The mRNA would be three nucleotides longer.

The insertion is before the start codon so theprotein would be the same size as normal.

No any change to amino acid sequence so same function as normal.
