Copyright ? 2011 Pearson Education, Inc. - 1 - Name_______________________ Period___________ Chapter 16: The Molecular Basis of Inheritance Concept 16.1 DNA is the genetic material 1. What are the two chemical components of chromosomes? DNA and protein 2. Why did researchers originally think that protein was the genetic material? Until the 1940s, the case for proteins seemed stronger, especially since biochemists had identified them as a class of macromolecules with great heterogeneity and specificity of function, essential requirements for the hereditary material. Moreover, little was known about nucleic acids, whose physical and chemical properties seemed far too uniform to account for

Biology, 7e (Campbell) Chapter 17: From Gene to Protein 7) Which of the following represents a similarity between RNA and DNA? D) nucleotides consisting of a phosphate, sugar, and nitrogenous base 9) Using RNA as a template for protein synthesis instead of translating proteins directly from the DNA is advantageous for the cell because B) RNA acts as an expendable copy of the genetic material, allowing the DNA to serve as a permanent, pristine repository of the genetic material. C) many mRNA molecules can be transcribed from a single gene, increasing the potential rate of gene expression. D) B and C only

Campbell's Biology, 9e (Reece et al.) Chapter 20 Biotechnology The new questions in Chapter 20 cover all of the chapter?s concepts and are primarily at the higher skill levels. In addition, the chapter presents several scenarios that are accompanied by a series of questions. Multiple-Choice Questions 1) Assume that you are trying to insert a gene into a plasmid. Someone gives you a preparation of genomic DNA that has been cut with restriction enzyme X. The gene you wish to insert has sites on both ends for cutting by restriction enzyme Y. You have a plasmid with a single site for Y, but not for X. Your strategy should be to A) insert the fragments cut with restriction enzyme X directly into the plasmid without cutting the plasmid.

4/2/13 1:14 PM DNA Deoxyribose Double Stranded (Double Helix) Nitrogenous bases (Cytosine, Guanine, Adenine, Thymine) RNA Ribonucleic Single Stranded Nitrogenous bases (Cytosine, Guanine, Adenine, Uracil) Both have phosphate Cytosine = Guanine Adenine = Thymine DNA Replication is semi conservative. DNA Replication happens during interphase. One strand determines the sequence of the other strand. DNA polymerase copies DNA strands in the 5?->3? direction. Transcription ? The first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme, RNA polymerase. Translation ? The process through which cellular ribosomes manufacture proteins. In DNA, T=A G=C In RNA, T=A G=C A=U Translation occurs in the cytoplasm.
