2
1 - 100
  • What important process contributes to the genetic
    diversity of an individual and occurs during
    Prophase I of Meiosis?
  • Crossing-Over between Homologous Chromosomes

3
1 - 200
  • Identify TWO disadvantages of Sexual Reproduction
  • Takes longer
  • Must find a mate
  • Takes more energy
  • Fewer offspring

4
1 - 300
  • Identify THREE organisms that reproduce asexually
  • Some plants (spider plants, willow trees, ect.)
  • Bacteria
  • Sea stars, sea urchins, some worms

5
1 - 400
  • What type of cell division creates FOUR haploid
    gametic cells?
  • Meiosis

6
1 - 500
  • If an cell has a diploid number of 46 before
    meiosis, how many chromosomes are present in each
    daughter cell.
  • 23

7
2 - 100
  • Which Mendelian Law is described below
  • Two tall parent plants have a short plant
    offspring
  • This law states that alleles will be separated
    from each other during the process of Meiosis
  • Law of Segregation

8
2 - 200
  • Mendelians Law of Dominance
  • A tall plant is crossed with a short plant and
    the offspring have the following phenotypes
  • 3 tall plants, 3 short plants
  • What is the genotype of the parent plants?
  • Tt and tt

9
2 - 300
  • If a man that is color blind and a woman that is
    a carrier have children what is the probability
    that their sons will be colorblind? Their
    daughters? (clue- draw out a Punnett square)
  • 50 chance that their son will be colorblind
  • 50 chance that their daughter will be colorblind

10
2 - 400
  • Given the information key to the right, what
    phenotypes would you expect to see if you crossed
    a red flower with a white flower?
  • What type of inheritance is exhibited?
  • Only pink flowers
  • Incomplete dominance

11
2 - 500
  • Is this disorder
  • dominant or recessive?
  • Is it autosomal or
  • sex-linked?
  • What is the genotype of the oldest male in the
    pedigree?
  • Dominant
  • Autosomal
  • Heterozygous

12
3 - 100
  • What is 9 in the picture to the right?
  • What kind of bond is 8?
  • Nucleotide
  • Hydrogen bond

13
3 - 200
  • True or False - During DNA Replication Adenine
    always base pairs with Uracil and Guanine always
    base pairs with Cytosine
  • FALSE

14
3 - 300
  • Why does the DNA need to be replicated?
  • A) It has become mutated
  • B) To make an RNA molecule
  • C) The cell is going to divide and needs two
    copies
  • D) So that one copy can leave the nucleus and
    make proteins
  • C) The cell is going to divide and needs two
    copies

15
3 - 400
  • DNA replication results in two DNA molecules,
  • A) each with two new strands
  • B) one with two new strands and the other with
    two original strands
  • C) each with one new strand and one original
    strand
  • D) each with two original strands
  • C) Each with one new strand and one original
    strand

16
3 - 500
  • What enzyme adds nucleotides to the new DNA
    strand during DNA Replication?
  • DNA Polymerase

17
4 - 100
  • What is the complementary strand of mRNA for this
    segment of DNA?
  • TACGGCCTA
  • How many amino acids will this code for?
  • AUGCCGGAU
  • 3

18
4 - 200
  • Which important RNA molecule has an anticodon and
    holds an amino acid?
  • tRNA

19
4 - 300
  • Where does Translation take place?
  • What is the end product of translation?
  • Ribosome (cytoplasm)
  • Polypeptide (protein)

20
4 - 400
  • Where in a Eukaryotic cell is mRNA created?
  • What is the process of creating mRNA called?
  • The Nucleus
  • Transcription

21
4 - 500
  • What does Gene Regulation mean?
  • Cells dont make all of the proteins all of the
    time. They only make the ones they need.

22
5 - 100
  • If a mutation occurs in a somatic cell (not a sex
    cell)
  • A) it will be spread to the family
  • B) it will cause immediate death
  • C) a fetus will not develop properly
  • D) it could cause skin cancer
  • D) it could cause skin cancer

23
5 - 200
  • Identify TWO diseases or disorders caused by
    genetic mutations that are sex-linked
  • Colorblind
  • Muscular Dystrophy
  • Hemophilia

24
5 - 300
  • What happens if a single pair of homologous
    chromosomes dont fully separate during Meiosis,
    and the gamete is fertilized?
  • You end up with a monosomy or a trisomy

25
5 - 400
  • Identify TWO examples of Biotechnology that
    select for useful traits.
  • Oil metabolizing bacteria created by
    encouraging mutations with radiation
  • Insect resistant plants created by splicing
    genes into a different genome
  • Polyploidy crops created by encouraging
    non-disjunction
  • Larger corn plants created by selective breeding

26
5 - 500
  • Identify TWO autosomal chromosomal disorders.
  • Sickle Cell Anemia
  • Huntington's
  • Cystic Fibrosis
  • Down syndrome
