SOPHIA_HUMAN_BIOLOGY_UNIT_6_MILESTONE 2020 - South New Hampshire University HUMAN BIOLOGY UNIT 6 MILESTONE 1 Being left-handed (represented as l) is a recessive trait. Jim and Suzie are both left-h... anded. If they have a child, which of the following could be his/her genotype? • Either Ll or ll • LL • Ll • ll CONCEPT Punnett Squares 2 What do all nucleotides have? • A five-carbon sugar, a nitrogen group and a phosphorous base • A five-carbon sugar, a phosphate group and a nitrogenous base • A five-carbon sugar, an amino acid and a peptide bond • Six-carbon monosaccharides bonded together in long branching chains CONCEPT Structure of DNA and Chromosomes 3 The final phase of translation, called termination, is signaled by three nucleotides, called a __________, that mark the end of a polypeptide chain. • stop codon • plasmid • https://www.coursehero.com/file/63413705/HUMAN-BIOLOGY-UNIT-6-MILESTONEpdf/ This study resource was shared via CourseHero.comexon • intron CONCEPT Protein Synthesis, Part 2: Translation 4 Which of the following statements is true about recombinant DNA? • It contains DNA from more than one species. • All of the answer choices are correct. • It is used in genetic engineering. • It utilizes bacterial plasmids. CONCEPT DNA Technology and Research 5 What is the gene that goes with a trait called? • Phenotype • Genotype • Heredity • Recessive allele CONCEPT Heredity 6 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? • 50% https://www.coursehero.com/file/63413705/HUMAN-BIOLOGY-UNIT-6-MILESTONEpdf/ This study resource was shared via CourseHero.com• 25% • 0% • 100% CONCEPT X-Linked Traits 7 Which of these is an autosomal recessive disorder that can result in mental retardation if levels of a certain amino acid get too high? • Cystic fibrosis • Down syndrome • Huntington's disease • Phenylketonuria CONCEPT Autosomal Recessive Traits and Disorders 8 How genes are expressed can be influenced by factors outside the body, like diet. What are the resulting phenotypes called? • Penetrance • Pleiotropy • Multifactorial trait • Polygenic trait CONCEPT Polygenic Traits and Pleiotropy 9 https://www.coursehero.com/file/63413705/HUMAN-BIOLOGY-UNIT-6-MILESTONEpdf/ This study resource was shared via CourseHero.comWhich phase of mitosis follows prophase? • Metaphase • Telophase • Interphase • Anaphase CONCEPT Mitosis 10 A fiber that consists of microtubules and connects chromosomes to the poles of the cells during cell division is called the __________. • spindle • centriole • centrosome • centromere CONCEPT Mitosis 11 Cri-du-chat is an example of what kind of genetic mutation? • Deletion • Duplication • Environmental • Translocation https://www.coursehero.com/file/63413705/HUMAN-BIOLOGY-UNIT-6-MILESTONEpdf/ This study resource was shared via CourseHero.comCONCEPT Chromosome Structure Changes 12 Which of the following does DNA replication produce? • One molecule with extra DNA, causing the nucleus to divide • New RNA only • New DNA only • Two molecules, each of which is half new and half old DNA CONCEPT DNA Replication 13 Which of the following is true of crossing over? • It occurs in meiosis I. • It increases genetic variability. • It involves the exchange of chromosome segments between homologous chromosomes. • All of the choices are correct. CONCEPT Meiosis and Genetic Variability 14 Which of these is true about a clone? • It is a hybrid version of two different cell types. • It is a white blood cell infected by a virus. • It is a type of cancerous stem cell. https://www.coursehero.com/file/63413705/HUMAN-BIOLOGY-UNIT-6-MILESTONEpdf/ This study resource was shared via CourseHero.com• It is a genetic copy of a cell. CONCEPT DNA Technology and Research 15 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? • Another gene caused the alleles for blonde hair to deactivate. • Blonde hair is not actually a recessive trait. • It's not actually possible for two parents with recessive phenotypes to have a child with a dominant phenotype. • One parent has a dominant allele for blonde hair and a recessive allele for brown hair.
