PREP GUIDE FOR QUIZ #3
Last part of Ch. 21 (DNA and Biotechnology)
Most of Ch. 4 (Body Organization, Homeostasis,
and the Integumentary System)
First part of Ch. 5 (The Skeletal System)
TO FOCUS YOUR STUDYING EFFORTS:
Quiz #3 (which will take place at the beginning of the lecture period Tuesday, January 27th) will cover the content of
my lectures from the slide titled “Transcription” of the Ch. 21 slides through the slide titled “Endochondral
ossification” of the Ch. 5 slides.
PRACTICE TEST QUESTIONS:
The following are multiple choice questions that are similar in content, scope, and difficulty to the questions that
will appear on the actual weekly quizzes and final exam. There will be no key provided—all answers can be
deduced by referencing your lecture notes and Goodenough textbook. Trust me: looking up the answers to these
questions to see how you’ve done is a valuable form of studying…as is making up your own exam questions and
quizzing each other on them. More work for you in the short term, but you’ll thank me later! ☺
MULTIPLE CHOICE QUESTIONS – Circle the best answer.
