1 - $100 How many gametes are produced from one cell during meiosis? 4

1 - $200 What happens during the four stages of mitosis? (PMAT) Nuclear envelope disappears, chromosomes line up, homologous chromosomes separate, and nuclear envelope reforms

1 - $300 What is produced during mitosis? What is produced from meiosis? Body cells; gametes (sex cells)

1 - $400 How many chromosomes does a diploid human cell have? 46 (or 23 pair)

1 - $500 What is genetic variation? Traits (hair color, height, skin color) differ among individuals

2 - $100 What is heredity? The passing of traits from one generation to the next

2 - $200 Write out the genotype for a homozygous tall pea plant (T is tall, t is short) TT; remember—homozygous is the same as purebred.

2 - $300 What is the phenotype of the offspring produced from a cross between a purebred tall pea plant and a purebred short pea plant (Hint: make a Punnett square) All offspring will be tall (Tt is genotype)

2 - $400 Draw a pedigree. The mother carries the trait, and the father is also a carrier. They have one son who expresses the trait and a daughter who is a carrier. Draw on board

2 - $500 What is the genotype of the first son in the second generation. (use the letter H) hh

3 - $100 When DNA is replicated, where does the original strand go? Half of the old strand goes to each of the two new strands

3 - $200 What are the three components of a nucleotide? Sugar, phosphate, and a nitrogen base

3 - $300 What is the model of DNA that Frances and Crick created? The double helix model

3 - $400 In DNA, which nitrogen bases pair together. Adenine and thymine. Cytosine and guanine.

3 - $500 What does the sequence of nucleotides in DNA molecules determine? Our genes and traits. This sequence makes up who we are as unique individuals.

4 - $100 What is a codon? A three-base “word” that codes for an amino acid

4 - $200 What do amino acids make? Proteins

4 - $300 Where are proteins made? Amino acid chains are assembled at the ribosome

4 - $400 What are mutations? Changes in the sequence of nucleotides

4 - $500 Not really a protein synthesis question, but what are transgenic organisms? They contain genes from another species

5 - $100 What are some benefits of genetic engineering? Creating better crops and livestock; other answers are possible as well.

5 - $200 Which type of point mutation is worse: a substitution of a base pair or a deletion of a base pair? A deletion because it will change every amino acid after the mutation

5 - $300 Cross a Tt with a Tt. What percentage of offspring will be homozygous recessive? 25%

5 - $400 What is the purpose of mRNA? To carry messages from DNA to the ribosome for protein synthesis

5 - $500 When can mutations be passed from parent to offspring? When the mutation is in the sex cell (not the body cell)

Final Jeopardy What are some factors or processes that lead to variation in a species? Good examples: environment, mutations, sexual reproduction
