  3. DD Daily Double

  4. $100 In the process of meiosis what happens to the number of chromosomes? It is cut in half If you start with 46 you get 23

  5. $200 What cells are made in meiosis? Egg and sperm

  6. $300 What is the purpose of crossing over? It increases genetic variation

  7. $400 What is the difference between haploid & diploid? Diploid - 2 sets of chromosomes Haploid - one set of chromosomes (created in meiosis)

  8. $500 A human has 23 chromosomes in its haploid egg and sperm cells. How many chromosomes are in its diploid body cells? 46

  9. A mom & a dad have type A blood. What blood types could their children have? A or O

  10. Red petals (R) are dominant to white petals (r). You perform a test cross between a red-petaled flower (genotype unknown) and a white-petaled flower. The test cross produces 5 red flowers and 4 white flowers. What is the genotype of the red-petaled flower? Rr

  11. Which parent determines the sex of the child? Why? Male because he has XY chromosomes and a female is XX so she only has a X to give

  12. What is the difference between heterozygous & homozygous? heterozygous - two different letters Aa homozygous - two of the same letters aa or AA

  13. B - Black b - White T - tall t - short What is the genotype and phenotype of the ??? box? ??? bt BT Bt bT BT Bt bT bt Geno - BbTt Pheno - Tall & Black

  14. $100 What is caused by a mutagen? change in the DNA structure

  15. If the original strand of DNA is ATCG What is the complementary strand? TAGC

  16. What part of DNA carries the code? the nitrogen base

  17. Is a mutation helpful, harmful or neutral? It can be any of them

  18. Why does DNA replication need to happen? So when the cell goes through mitosis each new daughter cell will have the same chromosomes

  19. $100 What are the building blocks of proteins? Amino Acids

  20. If the mRNA is AUCG...What is the DNA? TAGC

  21. U C A G U Phenylaline Phenylaline Leucine Leucine Serine Serine Serine Serine Tyrosine Tyrosine Stop Stop Cysteine Cysteine Stop Tryptophan U C A G C Leucine Leucine Leucine Leucine Proline Proline Proline Proline Histidine Histidine Glutamine Glutamine Arginine Arginine Arginine Arginine U C A G A Isoleucine Isoleucine Isoleucine Methionine Threonine Threonine Threonine Threonine Asparagine Asparagine Lysine Lysine Serine Serine Arginine Arginine U C A G G Valine Valine Valine Valine Alanine Alanine Alanine Alanine Aspartic acid Aspartic acid Glutamic acid Glutamic acid Glycine Glycine Glycine Glycine U C A G If the mRNA is AUGGCA... What are the amino acids? Met Ala

  22. A gene is a piece of DNA that contains the instructions to make a single ________. protein

  23. Starting with the mRNA in the nucleus describe protein synthesis. mRNA copies the DNA mRNA leaves the nucleus and goes to a ribosome tRNA lines up with the mRNA and brings in an amino acid when the amino acids are all lined up you created a protein

  24. $100 What is gene sequencing? finding the order of nitrogen bases within a gene

  25. Why would one use DNA fingerprinting to identify a criminal or in a paternity suit? DNA from individuals is unlikely to be the same

  26. What is genetic engineering? Moving the chromosomes of one organism into another organism

  27. What is recombinant DNA? The DNA formed when you combine DNA from two different organisms

  28. Why is a base substition less harmful than a base deletion or insertion? A substitution would change at the most one amino acid. A deletion/insertion would change every amino acid after the mutation

  29. $100 The Teddies What is the name of the RHS dance team?

  30. What is the oldest evidence that evolution scientists use to support evolution? fossils

  31. What is microevolution? A change within a species over time

  32. According to macroevolution, what do the similarities in these bone structures point to? Whale Bat Human Cat common ancestory

  33. The whale’s pelvis shows evidence that it may have walked on land. The whale no longer uses the pelvis for walking. The whale pelvis is considered to be a ___. Vestigial Structure

  34. Final What is the function of the endocrine system? Final Jeopardy
