Assignment task: In previous work, we have stressed that the basic DNA structure and the specific bases found in DNA (G, T, A, C) are found in all living organisms.
Now we want to consider how useful the specific combinations of those base pairs can be in evaluating genetic relationships between organisms and as an identification tool for single organisms.
You will need to review The Power of Base Pairs narrated PowerPoint to answer these questions.
1. What is the probability of seeing the following base pairs sitting next to each other at a specific location in a human? Would the probability be different if you saw this combination in an earthworm or a maple tree? G G C A A
2. Why were plants moved below the fungi in the phylogeny discussed in the lecture?
3. How are base pairs a useful tool for law enforcement officers?
4. Why do you think DNA seems so difficult for people to understand? (I'm curious about your opinion!)
