CONCEPT DNA Technology and Research 2 Edgar and Alice both have blonde hair , which is a recessive trait. But their first child has brown hair. What is the most likely explanation? CONCEPT Punnett Squares 3 What do all nucleotides have? • A five-carbon sugar, an amino acid and a peptide bond • Six-carbon monosaccharides bonded together in long branching chains • A five-carbon sugar, a nitrogen group and a phosphorous base • A five-carbon sugar, a phosphate group and a nitrogenous base CONCEPT Structure of DNA and Chromosomes 4 Which of these is true for mitosis? CONCEPT Mitosis 5 Which of the following does DNA replication produce? New RNA only CONCEPT DNA Replication 6 What is an observable characteristic? (e.g. a person's height or skin color) CONCEPT Heredity 7 What best describes reproductive cloning? CONCEPT DNA Technology and Research 8 Which of these chromosome abnormalities results in multiple sets of the same sequence of nucleotides? Duplication • Translocation • None of these • Deletion CONCEPT Chromosome Structure Changes 9 A father has red-green colorblindness, his wife does not, nor is she a carrier. What are the odds that their daughter is a carrier for red-green colorblindness? CONCEPT X-Linked Traits 10 Molecules called have the ability to determine the speed at which transcription takes place. • transfer RNA CONCEPT Protein Synthesis, Part 2: Translation 11 Being left-handed (represented as l) is a recessive trait. Jim and Suzie are both left-handed. If they have a child, which of the following could be his/her genotype? CONCEPT Punnett Squares 12 How genes are expressed can be influenced by factors outside the body, like diet. What are the resulting phenotypes called? CONCEPT Polygenic Traits and Pleiotropy 13 Which of these is responsible for the occurrence of disjunction? CONCEPT Meiosis and Genetic Variability 14 Which phase of mitosis follows prophase?
