Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can
study here
.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

21. Cuts DNA in specific sites; the fragments created are usually predictable
Restriction enzymes
Advantages of Recom. DNA tech
Ericson Method
Modes of Selection
22. Theory of a stable - nonevolving population in which frequency of alleles do not change; only occurs in large - isolated populations with random mating - and no natural selection or mutations
Hardy- Weinberg equilibrium
Molecular similarity
Linnaeus
Artificial selection(breeding)
23. Invented the binomial method(naming of species); also believed that life was fixed
Lamarck
