Biol 101-DNA and Principles of Inheritance quiz1. Conceptually speaking, order the following structures from smallest to largest: DNA, gene,genome, chromosome, nucleotide.a. DNA, gene, genome, chromosome, nucleotideb. genome, DNA, chromosome, nucleotide, genec. nucleotide, gene, DNA, chromosome, genomed. gene, chromosome, nucleotide, genome, DNA2. Which of the following are living things? DNA, gene, genome, chromosome, cell,nucleotide.a. DNA, gene, and genomeb. chromosome and DNAc. cell, chromosome, and genomed. cell only3. Which structuresare considered the "basic unit of life" and the "basic unit of heredity"?a. The basic unit of life is the cell, and the basic unit of heredity is the gene.b. The basic unit of life is the cell, and the basic unit of heredity is the nucleotide.c. The basic unit of life is the protein, and the basic unit of heredity is the nucleotide.d. The basic unit of life is DNA, and the basic unit of heredity is the gene.4. What is a gene?a. the protein that results after translation is completeb. a segment of DNAthat is three nucleotides longc. a segment of DNA that carries a unit of informationd. one arm of a single chromosome5. Genes exist in pairs in cells. Where did each member of a pair of genes originate?a. one from each parent's gametesb. the duplication of chromosomes during the S phasec. crossing over during prophase Id. the growth during G1 produced each member of the pair6. What is wrong with this example? A heterozygous pea plant produces yellow seeds and itsgenotype is Yg, where Y representsthe dominant yellow seed allele and g represents therecessive green seed allele.a. The genotype should be presented as Gg because green is the recessive trait.b. A heterozygous pea plant with yellow seeds would have the genotype YY or yy.c. The correct genotype is Yy because yellow is the dominant trait.d. The genotype Yg would produce green seeds.7. Use your newfound knowledge of the inheritance of traits and Punnett Squares to predictthe chances that a Gg pea plant producing green pods and a gg peaplant producing yellowpods, when crossed with one another, will produce offspring with yellow pods.a. There is a 0-percent chance of this cross producing yellow pods.b. There is a 25-percent chance of this cross producing yellow pods.c. There is a 50-percent chance of this cross producing yellow pods.d. There is a 100-percent chance of this cross producing yellow pods.NOTE: Questions 8–13 refer to the offspring of the plant described in question 7.
