Biology Course Learning Objectives and Module Breakdown

Learning Objectives Overview

Introductory Module

  • Learning Goals:
    • Describe various properties defining life.
    • Correlate major environmental changes with key evolutionary innovations.
    • Identify major milestones in evolution and their chronological order in Earth's history.
    • Identify contributions of major evolutionary events to increasing biodiversity.
    • Define key terms:
    • Coevolution: a process whereby two or more species influence each other's evolutionary trajectory.
    • Adaptive Radiation: the evolution of diversity within a rapidly multiplying lineage, often in response to new opportunities or challenges in the environment.
    • Explain that the increasing complexity of organisms seen in the fossil record does not imply that evolution is goal-oriented.

Module 1

  • Learning Goals:
    • Discuss the importance of evolutionary theory to biology.
    • Describe contributions made by significant figures:
    • Linnaeus: Known for developing a hierarchical system for classifying organisms, establishing the binomial nomenclature.
    • Lamarck: Proposed early ideas of evolution, particularly the inheritance of acquired characteristics.
    • Malthus: Noted for his theories on population growth and its implications for resource scarcity, influencing Darwin's thoughts on competition.
    • Explain how Darwin and Wallace articulated the theory of evolution through natural selection, emphasizing how environmental pressures can influence the survival and reproduction of organisms.
    • Describe the Scientific Process and its significance:
    • Process of inquiry in science includes observation, hypothesis formulation, experimentation, and conclusion.
    • Distinguish between science and pseudoscience, focusing on empirical evidence and falsifiability.
    • Describe how multiple scientific inquiries converge to support evolutionary theory.

Module 2

  • Key Questions:
    • Why is understanding inheritance crucial for Darwin's theory of natural selection?
    • What were Darwin's views on inheritance?
    • Define Discrete Traits: traits that fall into specific categories (e.g., flower color).
    • Define Quantitative Traits: traits that show a range of variability (e.g., height).
    • Discuss Gregor Mendel's contributions to evolutionary theory, particularly the understanding of heredity and genetic variation in pea plants.
    • Identify the macromolecules that influence traits:
    • Includes DNA, RNA, and proteins.
  • Learning Goals:
    • Explain how carbon's electron configuration facilitates the formation of large, complex, and diverse organic molecules.
    • Describe variations in carbon skeletons and their contribution to organic molecular diversity and complexity.
    • Determine the properties of amino acids (i.e., whether they are nonpolar, polar, acidic, or basic) by analyzing their structures.
    • Describe the four levels of protein structure:
    • Primary: Sequence of amino acids in a polypeptide chain.
    • Secondary: Localized folding within protein due to hydrogen bonding (alpha helices and beta sheets).
    • Tertiary: Overall 3D structure of a polypeptide.
    • Quaternary: Arrangement of multiple polypeptide subunits into a larger complex.
    • Distinguish between:
    • Pyrimidine and Purine (types of nitrogenous bases in nucleic acids).
    • Ribose and Deoxyribose (sugars in RNA and DNA respectively).
    • Discuss structural features of a DNA molecule:
    • Double helix formation, base pairing, and the antiparallel nature of the strands.

Module 3

  • Key Questions:
    • Define Information Flow: the process through which genetic information is expressed as proteins in a cell.
    • Explain the relationship between genotype (the genetic makeup) and phenotype (the observable traits).
    • Define Gene: a segment of DNA that encodes a functional product, typically a protein.
    • Describe how genetic information is utilized to synthesize a protein through the processes of transcription and translation.
    • Explain the significance of base pairing between nucleotides in transcription and translation, contributing to fidelity in genetic information transfer.
    • Discuss the redundancy of the genetic code,
    • Redundant Genetic Code: multiple codons can code for the same amino acid, reducing the impact of mutations.
    • Discuss the universality of the genetic code across different organisms, indicating a common evolutionary origin.
  • Learning Goals:
    • Define the role of information flow in cellular function.
    • Describe the process of transcription:
    • Synthesis of RNA from a DNA template.
    • Describe the process of translation:
    • Synthesis of proteins from mRNA template with the help of tRNA.
    • Define the role of tRNA in translation, facilitating the correct incorporation of amino acids into a growing polypeptide chain according to the mRNA sequence.
    • Describe how nucleotide sequence alterations can result in polypeptide changes, which can impact organismal traits and function.

Example Questions

  • Define the following terms:
    • Codominance: a genetic scenario where both alleles contribute to the phenotype of the heterozygote.
    • Batesian Mimicry: a form of mimicry in which a harmless species imitates the warning signals of a harmful species to avoid predation.
  • Multiple Choice Question: Which of the following is NOT a required condition for Natural Selection?
