Study Notes
Exam Questions - Biology 110
- Multiple Choice Questions (MCQs): Exam comprises 32 MCQs, each worth 2 points.
- Short Answer Questions (SAQs): 4 SAQs, each worth 4 points. Students can skip one.
- Punnett Square Questions: 5 questions, each worth 4 points. Students can skip one.
- Freebies: Students can skip either one of the SAQs or one of the Punnett Squares.
Multiple Choice Questions (Example)
-
Question 1: Which protein controls cell cycle progression?
- Correct answer: Cyclins
-
Question 6: What are observable expressed traits?
- Correct answer: Phenotype
-
Question 7: Polyploid fruits are often...
- Correct answer: Larger (than diploid fruits)
-
Question 10: The kinetochore breaks down during?
- Correct answer: Anaphase
-
Question 12: What is the physical location of a gene on a chromosome?
- Correct Answer: Locus
Short Answer Questions (Example)
-
Question 33: Advantages of meiosis over asexual reproduction?
- Meiosis introduces genetic variation through recombination, while asexual reproduction produces genetically identical offspring. This variation is crucial for adaptation and evolution in changing environments.
-
Question 34: Consequences of checkpoint protein gene mutations?
- Mutations in checkpoint proteins can lead to uncontrolled cell division (cancer). This occurs because these proteins normally regulate the cell cycle ensuring DNA damage is fixed or the cell is properly prepared to divide.
-
Question 35: Dominant vs. recessive alleles in genetic diseases?
- Recessive alleles are more likely to be involved in genetic diseases. These diseases typically require both copies of the mutated gene to be present for the disease to manifest.
Punnett Square Questions (Example)
- Instructions: Show work. Failure to do so results in point deductions.
- Question 37-38: Incomplete dominance, red/white flower color, or fur color in mice require Punnett Square setups and calculations of offspring probabilities.
- Question 39: Blood type genetics problems require Punnett Square solutions to determine the probabilities of offspring blood types.
Other Topics
- Chromosome Structure & Function: Homologous chromosomes, sister chromatids, ploidy levels, and chromosome number.
- Genetic Laws: Independent assortment, dominance, and segregation (explanations required for some questions).
- Genetics Processes: Mitosis, meiosis, and mutation types.
- Meiosis: Stages of meiosis in mitosis, including prophase, metaphase, anaphase, and telophase.
- Mutations: Types of mutations (insertions, deletions, point mutations, etc.), and their effects.
- Sexual vs. Asexual Reproduction: advantages/disadvantages of each method.
- Inheritance Patterns: Concepts of autosomal traits, X-linked traits etc in genetics.
