Jeopardy Basketball Midterm Review 1. Q: If an organism’s somatic cells contain 10 chromosomes, how many chromosomes would be found in a zygote that organism produces? A: 10 (A zygote is a fertilized egg) 2 Q: What is a mutation? A: Change in the sequence of DNA. 3 Q: Give an example of how the environment can affect the phenotype of an organism. A: Twins separated at birth (phenotype = physical expression of genes) 4 Q: Construct and complete a Punnett Square for the following problem. Cross a homozygous dominant tall pea plant with a heterozygous pea plant. (tall = dom) 5 Q: Which form of cell division is utilized by bacteria? A: Mitosis 6 Q: Bacteria reproduce asexually. What is a pro and con of asexual reproduction? A: Pro – lots of offspring quickly Con – no genetic variation 7 Q: Which type of reproduction leads to variation in organisms? A: Sexual (unique combination of parent’s chromosomes) 8 Q: Relate the following terms in a sentence: DNA Gene Chromosomes A: Genes are composed of DNA and are found on chromosomes. 9 Q: Why is HIV so deadly? A: Attacks immune system, mutates quickly. 10 Q: How many daughter cells result from meiosis? A: 4 11 Q: Connect the following terms? Protein DNA RNA A: DNA is converted to RNA, and RNA provides the code for protein synthesis. 12 Q: What happens to people with sickle cell anemia? A: Mutation in DNA leads to a different amino acid…changes the shape of hemoglobin causing RBC’s to sickle. 13 Q: Which organelle controls what moves in and out of the cell? A: Cell membrane 14 Q: Why is the placenta so important in fetal development? A: It is where nutrients, wastes are exchanged between mom and baby. 15 Q: By what process are materials transported between mom and baby? (Hint: High  Low) A: Diffusion 16 Q: Through which process are clones created? A: Asexual reproduction (mitosis) 17 Q: Where are proteins made? What are they made of? A: Ribosomes, amino acids 18 Q: If 1 egg is fertilized by one sperm, then while the zygote is undergoing cleavage the zygote splits….you end up with A: Identical twins 19 Q: How does bacteria produce human insulin? A: Transformation…gene for insulin is transplanted from human to bacteria, bacteria multiply and produce insulin 20 Q: Create the DNA compliment for the strand of DNA below: ATCCGTTTAG A: T A G G C A A A T G 21 Q: Create the RNA compliment for the strand of DNA below: ATCCGTTTAG A: U A G G C A A A U C
