  1. a Mutation in the cell cycle
  2. b They are easily accessible
  3. c Built a 3D model of a DNA molecule
  4. d 1) They have very contrasting traits
    2) Can both self-pollinate and cross pollinate
    3) Easy to grow
  5. e Is a vaginal infection caused by a fungal organism causing discharge, vaginal itching, painful urination and can usually be cured by pre scripted medicine.

5 Multiple choice questions

  1. The process of change by which new species develop from preexisting species over time
    The idea of natural election if why evolution happens
    Individuals with traits advantageous to survival will produce more offspring
    Over time the number of individuals possessing those traits will increase in a population
  2. DNA polymerase- enzyme responsible for adding complementary bases to a replicating DNA molecule, also edits and corrects the replicating strand of DNA

    DNA helicase- enzyme responsible for unwinding the DNA strand and breaking H bonds between bases of DNA, allows for replication of the DNA molecule

    RNA polymerase- enzyme responsible for opening the DNA molecule at the promoter region of a gene, adds complementary bases according to base pairing rules for RNA until it reaches a stop location on the DNA, produces mRNA
  3. Overproduction- every population is capable of more producing more offspring than can survive
    Variation- exists in every population, is the variation of inherited traits
    Selection- individuals with specific traits are more or less likely to survive and have successful offspring
    Adaptation- traits that improve survival and reproduction will become more common
  4. 47 chromosomes
    Down's is caused by trisomy 21
    Caused by non disjunction of chromosomes during meiosis
  5. Spermatogenesis is for males and it goes through meiosis 1 and meiosis 2 to create 4 haploid gametes that change into sperm cells.

    Oogenesis is for females and it goes through 2 stages of meiosis to create 1 ovum and 3 other polar bodies.

5 True/False questions

  1. What are the types of DNA mutations? Describe eachdeletion- occurs when a piece of chromosome is lost

    duplication-occurs when a piece remains attached to its homologous chromosome after meiosis

    inversion- occurs when a piece reattaches to its original chromosome but in the reverse direction

    translocation- occurs when a chromosome piece breaks off and reattaches to a completely different non homologous chromosome

  3. Chapter 14The link between microevolution and macroevolution, and is the formation of new species

          

  4. What are the 3 types of RNA? Describe each.Point mutation- caused by change of a single nucleotide (usually silent mutation)

    Insertion or Deletion- caused by addition or subtraction of one or more nucleotides in a sequence (frameshift mutation)

    Silent mutation- caused by change in a nucleotide of a gene but that change has no effect on the protein produced (usually point mutation)

    Missense mutation- results when a codon is changed and causes a different amino acid to be put into the protein (replacement mutation)

    Frameshift mutation- caused by addition or deletion of nucleotides (insertion or deletion)

    Nonsense mutation- results when a codon for an amino acid if changed to a stop codon
    -amino acids usually cut short

          

  5. Chapter 1Mutation in the cell cycle
