1 Klug, Concepts of Genetics 8/e CHAPTER 1 MEDIA REVIEW QUESTIONS 1. The functional unit of heredity is a HINT: These units of inheritance control the pea plant traits that Mendel studied. a.Nucleus b.Chromosome c.Nucleotide d.Gene 2. True or false? The set of alleles for a given trait carried by an organism is called the organism’s phenotype. HINT: Review the difference between genotype and phenotype. 3. What are the basic subunits of DNA and RNA? HINT: These subunits constitute the genetic code. a.Ribosomes b.Proteins c.Nucleotides d.Amino acids 4. What is the central dogma of biology? HINT: How does information flow in an organism? a.DNA RNA protein b.DNA protein RNA c.RNA DNA protein d.Protein RNA DNA 5. Why are enzymes crucial to living organisms? HINT: Consider the function of enzymes in a cell. a.They are responsible for translating the genetic code stored in RNA into a sequence of amino acids. b.They transport molecules into and out of the cell. c.They repair DNA damage. d. They act as biological catalysts. 6. Which term describes the entire collection of DNA contained within an organism? HINT: The study of the DNA contained within an organism has developed into its own discipline in recent years. a.Clone b.Transgenic c.Genome d.Gene 7. True or false? The Human Genome Project seeks to determine the sequence of nucleotides in the human genome. HINT: The Human Genome Project is a federally funded international effort.

All of the following are desirable qualities in a model organism except HINT: Model organisms are used to study basic biological processes. a.Common genetic mechanisms with other organisms b.Long life span c.Ease of growth d.Production of many offspring 10. True or false? Mammals are the only good model organisms in which to study human diseases. HINT: Think about the model organisms used in a laboratory. 11. Mendel's work showed HINT: Mendel’s work in pea plants involved the principles of transmission genetics. a.That pea plants had unique patterns of inheritance b.The quantitative patterns underlying inheritance c.That certain genes are linked d.That genetics and evolution are linked 12. Which of the following errors are sources of genetic variation? HINT: Which of the following errors is heritable? a.Errors in translation b.Chromosomal aberrations and gene mutations c.Errors in transcription d.Damage to the DNA 13. Proteins are made up of 20 different amino acids. If the genetic code were made up of two- letter "words," what is the maximum number of amino acids there could be?
