Campbell's Biology, 9e (Reece et al.) Chapter 17 From Gene to Protein The text for Chapter 17 has remained largely unchanged from the previous edition. However, one-third of the following questions are new, and considerably more are at the skill level of analysis and application. Multiple-Choice Questions 1) Which of the following variations on translation would be most disadvantageous for a cell? A) translating polypeptides directly from DNA B) using fewer kinds of tRNA C) having only one stop codon D) lengthening the half-life of mRNA E) having a second codon (besides AUG) as a start codon Answer: A Topic: Concept 17.1 Skill: Application/Analysis 2) Garrod hypothesized that "inborn errors of metabolism" such as alkaptonuria occur because

The Backbone of Biological Molecules [[Page.58]] Although living organisms use water as their universal medium for life, they are made up of chemicals based mostly on the element carbon. Carbon enters the biosphere through the action of plants in the transformation of CO2 Of all chemical elements, carbon is unparalleled (best) in its ability to form molecules that are large, complex and diverse (various), and this molecular diversity had made possible the diversity of organisms that have evolved on Earth.

AP Biology Essay Questions The following is a comprehensive list of essay questions that have been asked on past AP exams. The questions are organized according to units. The lab-based questions have been removed. Unit 1 (Basic Chemistry and Water) 1. The unique properties (characteristics) of water make life possible on Earth. Select three properties of water and: a for each property, identify and define the property and explain it in terms of the physical/chemical nature of water. b for each property, describe one example of how the property affects the functioning of living organisms. Unit 2 (Organic Chemistry, Biochemistry, and Metabolism) 2. Describe the chemical composition and configuration of enzymes and discuss the

Glossary of Biochemistry and Molecular Biology 3' end/5' end: A nucleic acid strand is inherently directional, and the "5 prime end" has a free hydroxyl (or phosphate) on a 5' carbon and the "3 prime end" has a free hydroxyl (or phosphate) on a 3' carbon (carbon atoms in the sugar ring are numbered from 1' to 5'. That's simple enough for an RNA strand or for single- stranded (ss) DNA. However, for double-stranded (ds) DNA it's not so obvious - each strand has a 5' end and a 3' end, and the 5' end of one strand is paired with the 3' end of the other strand (it is "antiparallel"). One would talk about the 5' end of ds DNA only if there was some reason to emphasize one strand over the other - for
