Chelsea Claverie MCB 1310 February 10, 2015 Exam 1 Review: DNA polymerase ? involved in the replication of DNA, requires a ?primer? to initiate a new strand of DNA, faster at synthesis RNA Polymerase ? involved in transcription of DNA to mRNA, does not require a primer to start a new strand of RNA and will stop transcription with it encounters a stop codon

Ch 16 Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ 1. For a couple of decades, biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins, and not DNA. The reason for this belief was that proteins are more complex than DNA. This is because a. proteins have a greater variety of three-dimensional forms than does DNA. b. proteins have two different levels of structural organization; DNA has four. c. proteins are made of 20 amino acids and DNA is made of four nucleotides. d. Only A and C are correct. e. A, B, and C are correct. ____ 2. In his transformation experiments, Griffith observed that a.

Practice Problems for Molecular Biology, Session 2: DNA Replication Question 1 ATP ? a) Box the part that is added to a growing chain of nucleic acid. b) Star the atom(s) that can form a hydrogen bond with the complementary nitrogenous base. c) Circle the part of the molecule that decreases the stability of RNA as compared to DNA. d) Draw an arrow to the part of this molecule that you would modify to prevent further elongation. Indicate what change you would make next to the arrow drawn. Question 2 Consider the following origin of replication that is found on a chromosome. The sequence of region 1 is shown. Region 1: 5??CTGACTGACA?3?
