Activity 4
Simulate 3 different point mutations, 3 different insertion mutations, and 3 different deletion mutations starting from the original sequence of amino acids and explain why the protein product stays the same after some point mutations, but changes after others. Take pictures of the screen for all nine mutations and insert them below. Describe the mutation and explain the effect on the peptide.
Point mutation 1
Point mutation 2
Point mutation 3
Insertion mutation 1
Insertion mutation 2
Insertion mutation 3
Deletion mutation 1
Deletion mutation 2
Deletion mutation 3
Activity 5
Step 1: Design a protein product that consists of mainly hydrophilic amino acids. Take pictures of the screen and insert them on the lab manual template.
Step 2: In order for a protein to be exported out of the cell, the head needs to be hydrophobic. Design a protein with a hydrophobic head of at least four amino acids. Take pictures of the screen in the simulation of the protein you have designed and insert them on the lab manual template.
Why does the protein product stay the same after some point mutations, but change after others?
