AP Biology Chapter 21 Genomes and Their Evolution Overview ? Reading the Leaves form the Tree of Life Scientists are now able to compare different species by comparing their DNA We have sequenced the full DNA of many different species now By comparing, we can: study the set of genes that control group defining characteristics Learn about the long evolutionary history of shared ancient genes and their products (by looking at the genome of more different species such as bacteria, fungi, etcs and comparing to animals/humans.) Genomics: The study of whole sets of genes and their interactions. Bioinformatics: a new field ? the application of computational methods to the storage and analysis of biological data.

Molecular Biology Unit Exam Question 1 Consider the following origin of replication that is found on a chromosome. The sequence of region 1 is shown below. Region 1: 5??CTGACTGACA?3? 3??GACTGACTGT?5? 3? 5? 5? 3? Region 1 top ? ori bottom ? a) Within Region 1, which strand will be the template for leading strand synthesis, the top or the bottom? b) If we assume that a lagging strand fragment is made from region 1, what will be its sequence? c) You examine DNA replication in an E. coli mutant, which has a partially defective DNA polymerase. In vitro experiments using the mutant DNA polymerase gives an error rate of 10-3, as compared to the expected error

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
