DNA Sequencing Graph

 

As you can see in the graph Abby and Bob are both 97% from normal and Carol is 58%. Abby has point mutation wrong with his DNA. this means that one point is wrong with his.Bob has truncation mutation. This means one point is wrong with his but that point caused the DNA to add a stop. so everything after the stop doesn't matter. so really Bob is 79%. the last is carol she is at 58% because she has a frame shift mutation. one letter was missing so all the rest of the letters shifted over and made her entire DNA wrong. All three people have a chance of having a disease but we don't know them so we can't tell. We are pretty sure carol has a disease though.
