1. During the lesson, you analyzed the DNA sequence of the housefly. For which of the following organisms would you expect the DNA sequence to be least similar to the housefly’s? (1 point)
butterfly
grasshopper
monkey
beetle
2. Why is PCR a necessary step in the analysis of a DNA sample taken from a crime scene? (1 point)
The sample yields very little DNA, which means that it must be amplified to produce enough quantity to detect on a gel.
The sample may be contaminated, which means that the DNA of intere
