one nucleotide is mistakenly replaced by another, A with G for example. Let’s try an insertion mutation to see if it works! Substitution Point Mutation: Using the codon chart, transcribe and translate the following mutated DNA sequence (you will need to look at the amino acid that corresponds to each letter).

2. Which type of mutation results in abnormal amino acid sequence? 3. Which type of mutation stops the translation of the mRNA? 2. A geneticist found that a particular mutation had no effect on the protein coded by a gene. What do you think is the most likely type of mutation in this gene? Why? 4. Examine your genetic code chart.

b. Is this an example of a nonsense (doesn’t make any sense at all anymore), a missense (part of it doesn’t make sense and it might work ok), or frameshift mutation (bases had to move to make room for an insertion or deletion)? 2. An insertion occurred between the fifth and sixth codons when two new nucleotides were inserted.
