1- The following Wild Type DNA codes for color in a lizard living in the Namib Desert (tan sand) a skin colorof reddish brown. This lizard is preyed upon by hawks flying above.Wild Type (Normal) DNADNA Template Strand: TAC-TTC-AAA-CCG-ATTDNA (silent strand): ATG-AAG-TTT-GGC-TAA For number 7, compare this change to the wild type in number 1. Remember that the originalpigment is a different color.7. Let us assume that the following protein (Met-Lys-Phe-Ser) changes the pigment deposited inthe lizard skin to a tan color. Would this be detrimental? Would this be beneficial? Explaineither answer.
