Q1. Give the series of any six-base-pair DNA molecule that can be affected by aminopurine. Then show the results of replication if aminopurine were incorporated in one place during replication of one of the strands and paired with cytosine. Show the results of replication for the affected strands for as many generations as necessary till the mutation becomes fixed.
Q2. What chemical property of the leucine residues thought to form tight ring that prevents the passage of ions within the channel of the acetylcoline receptor suits them for this role?
